- When it is feasible to do so, what are the advantages of moving the execution of the process to the input/output queue first? In the case that the input/output signal is broken, what do you believe will take place? Will this decrease the highest burst rate that the CPU is capable of achieving? What exactly do you mean by saying that? I'm not quite sure I get it.When feasible, what advantages does it have to move process execution to the I/O queue first? Should the I/O connection go down, what do you anticipate would happen? Will this reduce the CPU's maximum burst frequency in any way? Not sure I understand what you mean by that.How would it be advantageous to prioritize the I/O queue above the process execution queue? What will happen if the I/O is interrupted is anyone's guess. Indications are conflicting as to how this could effect the maximum burst rate of the CPU. I'm confused as to the nature of your question.
- Computer Science Suppose for a processor system it takes 35 cycles to push and pop registers onto the stack and change the PC value to the start of the interrupt service routine (ISR) or return from it. Suppose also that the ISR software takes additional 45 cycles to store the process state before the actual ISR body begins its work, and suppose it takes the same number of cycles to restore the process state when ISR is finished. If the ISR body takes 1000 cycles, what is the percent total overhead every time the ISR is executed? If the processor is running at a 2 GHz clock frequency, how long does it take before the ISR body begins execution in nanoseconds? This is usually called the ISR latencyHow would it be advantageous to prioritize the I/O queue above the process execution queue? If the I/O connection fails, who knows what will occur. No one knows how this could effect the CPU's maximum burst rate. I'm confused as to the nature of your question.Consider a CPU which operates with 20Mbyte/s operating speed. The CPU is operating on program control mode of I/O and it has to transfer data of 20 bytes from it. The data is transferred byte wise. Size of the Status register is 2 bytes. What is the total time needed to perform the data transfer?
- Consider a computer with cache, DRAM, HDD memory hierarchy. The hit rate of cache is 90% and DRAM is 95%. Read latencies of cache, DRAM, and HDD are 5ns, 100ns, and 1ms respectively. What is the average latency of executing an instruction involving a memory read? Express your answer in micro-seconds. Round it to the nearest integer. Enter your answer hereSuppose we have a benchmark that executes in 100 seconds of elapsed time, of which 90 seconds is CPU time and the rest is 1/0 time. Suppose the number of processors doubles every two years, but the processors remain the same speed, and I/O time doesn't improve. How much faster will our program run at the end of six years?Registers are fast, but small memory locations that are inside of a CPU. They are used for the CPU's internal computations. A modern 32-bit CPU only contains 8 registers that we are capable of manipulating: EAX, EBX, ECX, EDX, EBP, ESP, ESI, and EDI. Each of these is a 32-bit register (meaning they each hold 32 digit binary numbers). There are many situations where we would want to use smaller portions of data than 32 bits. For example, when working with characters we are primarily using byte data, since each character is stored in just a single byte (which you should know is 8 bits). For this purpose, portions of the 32-bit registers can be referenced directly as if they were smaller registers. The register EAX holds 32-bits. The register AX is the bottom half of EAX, holding just 16 bits. The register AL is the bottom half of AX, holding just 8 bits. There is also AH, which is the top half of AX and also holds 8 bits. EBX, ECX, and EDX can also be split up in the same manner using…
- Carefully read each sentence in this question. You may agree/disagree with each sentence (consider each sentence separately) if you have a good justification for doing so (not in more than 2 lines for each sentence). “A daisy chaining technique could result in starvation.” “The received data is saved in contiguous memory regions in DMA transfer.” “The most difficult method of device identification is multiple interrupt lines.” “An interrupt request takes longer for the CPU to handle than a DMA request.” “The architecture of InfiniBand operation is layered.”A modern computer central processing unit chip (CPU) runs with a clock speed of 2.7 GHz. It can execute one operation in each of these clock cycles. a. How many seconds long is one clock cycle? b. Electrical signals travel at the speed of light. How far can an electrical signal travel in one clock cycle? c. Wires between the CPU's control unit and its cache memory (both on this chip), are about 2 cm long. How does this compare to how far an electrical signal can travel in one clock cycle?A computer with a 32-bit 3.5 gigahertz scalar non- pipelined CPU needs to invert the colors of a 150 KB bitmap image file located in the RAM. To do this, each bit of the image must be complemented (Os are converted to 1s and vice-versa). Assume every instruction undergoes the following stages and each stage uses one CPU clock cycle: • Fetch • Decode • Read from memory • Execute • Write to memory Instructions: For this assignment, you must calculate how much time the computer will need to invert the image with a single-core and a dual core CPU. Show and explain your calculations and assumptions in a short paper and answer the following questions: • Will there be any parallel slowdown? Why or why not? Length: 2-3 page explanatory paper
