Micro Operations Microinstruction Micro Program Micro Code

Micro Operations Microinstruction Micro Program Micro Code Each microinstruction in a microprogram provides the bits which control the functional elements that internally compose a CPU. The advantage over a hard-wired CPU is that internal CPU control becomes a specialized form of a computer program. Microcode thus transforms a complex electronic design challenge (the control of a CPU) into a less-complex programming challenge. Microcode is a layer of hardware-level instructions and/or data structures involved in the implementation of higher level machine code instructions in many computers and other processors; it resides in a special high-speed memory and translates machine instructions into sequences of detailed circuit-level operations. It helps separate the machine instructions from the underlying electronics so that instructions can be designed and altered more freely. It also makes it feasible to build complex multi-step instructions while still reducing the complexity of the electronic circuitry compared to other methods. Writing microcode is often called microprogramming and the microcode in a particular processor implementation is sometimes called a microprogram. Microcode can be characterized as horizontal or vertical. This refers primarily to whether each microinstruction directly controls CPU elements (horizontal microcode), or requires subsequent decoding by combinational logic before doing so (vertical microcode). Consequently each horizontal microinstruction is wider (contains more bits) and occupies more storage space than a vertical microinstruction. Modern microcode is normally written by an engineer during the processor design phase and stored in a ROM and/or PLA structure, although machines exist which have some writable microcode in SRAM or flash memory. Microcode is generally not visible or changeable by a normal programmer, not even by an assembly programmer. Some hardware vendors, especially IBM, use the term as a synonym for firmware, so that all code in a device, whether microcode or machine code, is termed microcode (such as in a hard drive for instance, which typically contain both). Microcode was originally developed as a simpler method of developing the control logic for a computer. Initially CPU instruction sets were hard wired. Each step needed to fetch, decode and execute the machine instructions (including any operand address calculations, reads and writes) was controlled directly by combinatorial logic and rather minimal sequential state machine circuitry. While very efficient, the need for powerful instruction sets with multi-step addressing and complex operations (see below) made such hard-wired processors difficult to design and debug; highly encoded and varied-length instructions can contribute to this as well, especially when very irregular encodings are used. Q.2. How Information Technology can be used for strategic advantages in business? Ans.: All the advantages and disadvantages of information technology, it is essential that we know what information technology is exactly, and why it has it come to play such a important role in our daily lives. Today information technology involves more than just computer literacy; it also takes into account how computers work and how these computers can further be used not just for information processing but also for communications and problem solving tasks as well. Globalization IT has not only brought the world closer together, but it has allowed the worlds economy to become a single interdependent system. This means that we can not only share information quickly and efficiently, but we can also bring down barriers of linguistic and geographic boundaries. The world has developed into a global village due to the help of information technology allowing countries like Chile and Japan who are not only separated by distance but also by language to shares ideas and information with each other. Communication With the help of information technology, communication has also become cheaper, quicker, and more efficient. We can now communicate with anyone around the globe by simply text messaging them or sending them an email for an almost instantaneous response. The internet has also opened up face to face direct communication from different parts of the world thanks to the helps of video conferencing. Cost effectiveness Information technology has helped to computerize the business process thus streamlining businesses to make them extremely cost effective money making machines. This in turn increases productivity which ultimately gives rise to profits that means better pay and less strenuous working conditions. Bridging the cultural gap Information technology has helped to bridge the cultural gap by helping people from different cultures to communicate with one another, and allow for the exchange of views and ideas, thus increasing awareness and reducing prejudice. More time IT has made it possible for businesses to be open 24 x7 all over the globe. This means that a business can be open anytime anywhere, making purchases from different countries easier and more convenient. It also means that you can have your goods delivered right to your doorstep with having to move a single muscle. Creation of new jobs Probably the best advantage of information technology is the creation of new and interesting jobs. Computer programmers, Systems analyzers, Hardware and Software developers and Web designers are just some of the many new employment opportunities created with the help of IT. Q.3.What Characteristics of software make it different from other engineering products? Ans.: A large number of software standards have been developed concerned with software products and processes, terminology and more general fraework standards. While the need for software standards is not disputed, it is felt that many standards fail to take into account the essential differences, and occasionally the similarities, between software products and processes and other engineering products and processes. Ideally, standards should be useful, testable and represent a consensus view. It appears that some software standards fall significantly short of these objectives. Further progress in developing useful software standards requires a better understanding of the potential benefits which standards have, and do not have, to offer the software industry. The relevant issues are discussed and the next steps which should be taken in developing software standards suggested. Q.4. What are different addressing modes available? Ans.: Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs. The various addressing modes that are defined in a given instruction set architecture define how machine language instructions in that architecture identify the operand (or operands) of each instruction. An addressing mode specifies how to calculate the effective memory address of an operand by using information held in registers and/or constants contained within a machine instruction or elsewhere. In computer programming, addressing modes are primarily of interest to compiler writers and to those who write code directly in assembly language Absolute +-++ |jump| address | +-++ (Effective PC address = address) The effective address for an absolute instruction address is the address parameter itself with no modifications. Absolute/Direct ++++ | load | reg | address | ++++ (Effective address = address as given in instruction) This requires space in an instruction for quite a large address. Register +++++ | mul | reg1| reg2| reg3| reg1 := reg2 * reg3; +++++ This addressing mode does not have an effective address and is not considered to be an addressing mode on some computers. In this example, all the operands are in registers, and the result is placed in a register. Immediate/literal ++++-+ | add | reg1| reg2| constant | reg1 := reg2 + constant; ++++-+ This addressing mode does not have an effective address, and is not considered to be an addressing mode on some computers. The constant might be signed or unsigned. Implicit ++ | clear carry bit | ++ The implied addressing mode does not explicitly specify an effective address for either the source or the destination (or sometimes both). Either the source (if any) or destination effective address (or sometimes both) is implied by the opcode. Indexed absolute +++++ | load | reg |index| address | +++++ (Effective address = address + contents of specified index register) This also requires space in an instruction for quite a large address. The address could be the start of an array or vector, and the index could select the particular array element required. The processor may scale the index register to allow for the size of each array element. PART à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬B Q.5. How will you differentiate b/w Arrays and Stacks?Explain by giving an example. Ans: There are two main differences between an array and a stack. Firstly, an array can be multi-dimensional, while a stack is strictly one-dimensional. Secondly, an array allows direct access to any of its elements, whereas with a stack, only the top element is directly accessible; to access other elements of a stack, we must go through them in order, until we get to the one we want. Q.6. How Assembler differs from Complier? Ans.: An Assembler converts Assembly instructions into executable machine language. A Compiler converts higher level programming language instructions into Assembly instructions, and then those are turned into executable machine language. Most Compilers allow generation of object code, which is the Assembly instruction set generated by the Compiler. Some older Compilers allow for the Assembly instructions to be fine tuned by the programmer. Compiled programming languages typically generate many lines of Assembly instructions for each program statement. Some programming languages, such as ANSI C, are very close to Assembly, while others such as Java, result in many Assembly instructions per program statement. Most Compilers are highly optimized and it would be difficult for a human programmer to improve the efficiency of the output. Assembly level instructions are very difficult for someone not trained on Assembly to read and comprehend. Q.7. Out of Linear and Binary Search ,which one is preferred where and why? Ans.: Binary Search, because in Binary Search code take less no. of execution and it save time. But, in linear search it executes full time whenever search may give result. A binary search is an algorithm for locating the position of an element in a sorted list. It inspects the middle element of the sorted list: if equal to the sought value, then the position has been found; otherwise, the upper half or lower half is chosen for further searching based on whether the sought value is greater than or less than the middle element. The method reduces the number of elements needed to be checked by a factor of two each time, and finds the sought value if it exists in the list or if not determines not present, in logarithmic time. A binary search is a dichotomist divide and conquer search algorithm.

Nursing Exemplar Essay

I arrived to work well rested and ready to start the day. I had just returned after a two week long vacation. Because of the time off, I arrived to 7 East to find that the assortment of patients was not familiar at all. As I began getting reports on my patients, one in particular I started to feel a little anxious and stressed. At first glance I could tell I would be busy for the next twelve hours. Lynda was a 45 year old woman that was admitted almost a week ago after having an emergent tracheostomy placed. Lynda was newly diagnosed with laryngeal cancer with already having several other diagnoses including: seizure disorders, mild mental retardation, behavioral issues, and was legally blind. Lynda also lived in an apartment for assisted living, and her only support that was occasional present was her brother, Steven. That first day I have Lynda, she was started on a full liquid diet. It quickly became clear that she was aspirating food. She was very angry with me after I took away her first real meal she was having in 5 days. After the physicians came to see Lynda and she had a swallow evaluation preformed it was decided that the best option for Lynda would be to have a percutaneous endoscopic gastrostomy (PEG) tube placed, for feedings. Lynda was added to the schedule and had her PEG tube placed that day. She was not happy with me and blamed me. I explained to Lynda why she needed to have the PEG tube, she told me that she understood why, but just wanted to go home. I told her that we just had to look at this as another path she had to take in order to get home. I told her that if she was able to care for her tracheostomy that a PEG tube would be nothing. It was at about this point I learned that even though, she had already been on our floor for almost a week with what would be a permanent tracheostomy no one had yet taught her to suction herself. As they were calling for her to go downstairs for the PEG tube placement, I assured Lynda that she was strong and that she would be able to do this. I told her that I would be there when she came back, and I would be there all week to teach her. With that Lynda felt confident and off she went. As Lynda was having her PEG tube I was thinking about all the questions I had about Lynda. I started reading her history and physicals, and the clinic reports. The first clinic appointment she had was when she came in almost one week ago. At this visit she was told that she was not breathing adequately enough and it was because she had a large tumor that was starting to block off her airway. She was told that she need to have a tracheostomy and soon before it would close off her airway, and then she had two options radiation so see if it would shrink the tumor or surgery to remove the tumor. She agreed to have the tracheostomy and planed to have surgery as it was explained to be her best option. It really didn’t say if Lynda understood the full extent of the surgery she would have, she just saw it as something she had to do and then she could go home. While waiting for Lynda to come back I met her friend Sister Mary. Sister Mary told me all about Lynda, about how she has known her since she was a teenager and all the hardships that Lynda has gone though. Of the many things I learned about Lynda from Sister Mary was that Lynda was a trooper and she would be able to care for her tracheostomy and PEG tube. As my shift came to an end, and Lynda was still in recovery. I decided to write Lynda a note that state for her to get some rest because we had a busy day ahead of us tomorrow. Day two, my mission was to teach Lynda the basics of self suctioning. As I walked into her room this morning she was all smiles and told me she was ready to learn. We started with the basics showing and explaining her tracheostomy tube and the suction catheters to her. I then gave her a dummy doll we teach patients how to suction on, and she was able to show all the correct steps that I have taught her on the dummy. At this point in the day after lots of practicing Lynda was able to remove the inner cannula tube of her tracheostomy and clean it. The look on Lynda’s face was that of incredible confidence, I was truly impressed with her. By the end of our second twelve hour shift, Lynda had learned how to suction herself. It was passed along in report to simply encourage her independence in suctioning herself. Day three, my mission was to teach Lynda the proper care of her PEG tube, and to continue with the encouragement of her suctioning herself. After walking her though a bolus feeding in the morning, she agreed to do the next one. Lunch time came around and sure enough, she was able to complete the bolus feeding with minimum assistance. By the time came for the next feeding she was going to get the can of food to do it herself when I had walked in the room. She laughed and told me I was right that the PEG tube was a lot easier than suctioning. At this point in Lynda’s stay I knew that she would be going home soon. Later that evening, while discussing Lynda’s progress over the last few days with the physicians I asked them what the plan was and instructed them that we needed to get nutrition, social work, and case management involved so that she could go home. The physicians stated that they would place the consults that I requested but as for discharge they were unsure about when this would happen because Lynda’s brother doesn’t think she can care for herself on her own. I was shocked to hear this, the brother who I had not seen in the last three days, and from what I heard hadn’t even come to visit Lynda at all. I voiced my concerns with this to the physicians, and told them she has shown myself and other nurses her ability to care for herself, and maybe they should suggest that her brother come in and see her care for herself. I had their attention, and they called the brother to tell him all that she has done and suggested that he come in to see her new abilities because they would like to send her home. Before I left that evening I told Lynda about what the physicians had said and about her brother’s fears. I told her that it was now her time to shine if she wanted to go home and that I believed in her. After being off for two days, I was so delighted to hear that Lynda was going to go home that day. Lynda requested to have me be her nurse that day, from what I gathered she had been asking where I was. Her discharge went off like a breeze, everything fell right into place. Lynda told me that she was going to miss me, and I told her she would see me soon enough. She was coming back for her surgery in two weeks. When Lynda came back for her surgery, she had wrote me a letter, telling me that I was more that her nurse, I was her friend and that she was grateful I believed in her. Lynda had become a more difficult patient to have after her surgery, and she would need frequent encouragement to perform the tasks that we already knew she could do. It took Lynda a period of time to realize that all the nurse’s and not just I knew that she could do all these things. Once Lynda realized that it was her choice and responsibility, she started suctioning and feeding herself again. Even to this day Lynda comes to visit me on the floor when she comes in for her clinic visits. I always get a big hug and smile from her. She reminds me that the things I do every day as a nurse make such a positive impact on my patients. This experience taught to trust my instincts and to believe in my patients. I am no longer afraid to speak up with it comes to advocating for my patients. My role as an advocate for Lynda helped her to obtain her main goal of going home. I was able to offer support, guidance, and knowledge to help ensure that she would be able to care for herself in a safe manner.

Value And Its Influence On People s Living - 1533 Words

1. Introduction Money is very important to daily life. It is money that enable people to live a life they want to live and fulfill the value of life, such as happiness, health , love, and making difference. On the other hand, values determine every life decision that people makes (Determine the true purpose of money in your life, 2016). Value is the monetary worth of something, which has great influence on indivudual’s behavior and attitude. When a purchase decision is made, it involves a value calculation. In general, value is measured by price. But the price does not really reflect the true value. The most common value is economic value. Beside economic value, there are cultural value and social value. Value is important to both individual and business. This essay mainly explores the concept of value and its influence on people’s living. 2. The concepts of value 2.1 Definition of Value Value is defined as the desirability of something, such as usefulness and exchangeability, also is defined as the amount of money for a fair exchange for something (paperchain , nd). According to Adam Smith, the word â€Å"value†, had two different meanings: value in use and value in exchange.George [1908] mentioned that value of a thing was the largest amount of wealth that anyone was willing to exchange for. Mises [1934] added that value is always the result of subjective judgments, and intrinsically related to the worth that the consumer wanted to exchange for.
