Assume that a Line Printer and a Card Reader are directly connected to a Main Computer. a) If the Card Reader is capable of reading 1000 cards/m , a program consists on avearge 1500 cards and, the CPU is capable of processing 500 cards/sec. What is the CPU utilization percentage? b) Explain how the gap between the CPU and the I/O devices may affect the performance of such system.

Imagine that you have been given the responsibility of illustrating how the Memory Module, the I/O Module, and the CPU Module connect with each other and the rest of the computer. Do you feel that it is vital for you to highlight this message in an appropriate manner?

When a CPU interrupt is issued, the processor pauses what it is doing and processes the signal. Why should the operation be halted so that this action may be carried out? Let's take care of the interrupting process first, then complete the executing process afterwards. explain?
Assume you have a computer with no interrupt capabilities. What effect do you believe this might have on a computer's efficiency? Would a computer be able to function without the interrupt cycle?
1. System A takes 80 seconds to run a program. The same program takes 50 seconds to run on a new system B. What is the speedup provided by B over A? What is the performance improvement (percentage of performance improvement) of B over A? 2. Anna designs a 2.5 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of 1.25. Elsa is tasked with designing the company's next-generation processor and she comes up with an idea that improves the CPI of A to 1.1 and the CPI of B to 0.9. But the idea is so complex that the processor can only be implemented with a cycle time of 0.5 ns. Does Elsa's new processor out-perform Anna's processor on program A? How about on program B? 3. A program executes 200 billion instructions. It executes on an IBM processor that has an average CPI of 1.2 and a clock frequency of 4.0 GHz. How many seconds does the program take to execute? What is the cycle time of this IBM processor? Assume that an ARM processor…
There are several I/O devices connected to the CPU, and any one of them might potentially cause an interrupt at any time. Write out the four ways in which a processor may determine which devices generated the interrupt.
Should we use an asynchronous or synchronous bus to link the CPU to the memory? Describe your decision-making process.
There have been several suggestions made for a processor that, prior to carrying out encrypted data and system instructions, is able to decode the data and instructions. The data that has been submitted will next be encrypted by the processor. In what ways is the use of such a CPU beneficial? Which architectural requirements must be met by such a central processing unit?
In an eight-core system, multitasking is difficult due to the single memory channel. Hence, the next question is: "What can we do to solve it?"

Assume that a personal computer must get two pieces of data from its memory for every operation (one piece of data indicates which instruction to perform; the other is the information which is operated on). If the computer is the size of a typical PC, how long does it take to get these pieces of data? From this, what is the maximum rate at which the PC can execute instructions? Assume half the speed of light as travel rate.
Imagine that you have been given the responsibility of illustrating the manner in which the Memory Module, the I/O Module, and the CPU Module are all coupled with one another as well as the rest of the computer. Do you think it is necessary for you to emphasise the relevance of this message in the appropriate manner?
