Suppose that we are developing a new version of the AMD Barcelona proces- sor with a 4 GHz clock rate. We have added some additional instructions to the instruction set in such a way that the number of instructions has been reduced by 15% from the values shown for each benchmark in Exercise 1.12. The execution times obtained are shown in the following table. a. Name Execution Time (seconds) Reference Time (seconds) bzip2 700 9650 SPECratio 13.7 1.13.2 [10] In general, these CPI values are larger than those obtained in previous exercises for the same benchmarks. This is due mainly to the clock rate used in both cases, 3 GHz and 4 GHz. Determine whether the increase in the CPI is similar to that of the clock rate. If they are dissimilar, why?
Suppose we have two implementations:Machine A has a clock cycle time of 10 ns. and a CPI of 2.0. Machine B has aclock cycle time of 20 ns. and a CPI of 1.2. Which machine is faster for thisprogram, and how much in percentage? Consider that the total instruction in the program is 1x10^9 or about 1,000,000,000 set of instructions since the cycle time is running in nanoseconds.

Which computer is faster and how much? a) A is 1.33 times faster than B b) Bis 1.22 times faste than A c) Ais 1.23 times faster than B d) Bis 1.33 times faster than A Answer Submit
I am trying to better understand memory access in computers, please answer the sample question below. Assume that the page table can held in registers of the MMU. It takes 8 ms (milliseconds)to service a page fault if there is an empty frame or if the replaced page is not altered, and20 ms if the replaced page is altered. Memory access time is 100 ns (nanoseconds). It has been empirically measured that the page to be replaced is altered 75% of the time.Obtain the maximum probability of page fault for an effective memory access time ≤ 200ns.
(a) Find the length of each side of a square computer chip with 580 million transistors, if each transistor occupies a square of side 45 nm. (b) Find the number of transistors on a chip of the same size you found in (a) if the transistor size can be reduced to 32 nm on a side.
The following sequence of CPU bursts has been observed: 7, 5, 6, 15, 15, 15. (a) Using 7 as the initial estimate, So, generate the sequence of predictions, Si, for the corresponding observed values, T;, where 1
Suppose we could take the system of (Figure 1) and divide it into an arbitrary number of pipeline stages k, each having a delay of 300/k, and with each pipeline register having a delay of 20 ps. What would be the latency of the system? Express your answer in terms of k. What would be the throughput of the system? Express your answer in terms of k. What would be the ultimate limit on the throughput? Express your answer as in integer.
For the problems in this exercise, assume that there are no pipeline stalls and that the breakdown of executed instructions is as follows: add addi not beq lw sw 20% 20% 0% 25% 25% 10% In what fraction of all cycles is the data memory used?In what fraction of all cycles is the input of the sign-extend circuit needed? What is this circuit doing in cycles in which its input is not needed?
using RISC-V (RVS) if needed, answer the following both question, thumpsup if both what is the instruction with the following FUNCT3 (3 binary digits):001 The clock rate of a given CPU is 2.7 GHz and its CPI is 7.7. What is the number of instructions that the CPU executes per microsecond (in decimal)?
1. A program has 5 billion instructions is running with a CPI of 2 on a machine with a 2.5GHZ frequency, what is the execution time in seconds? 2. In a program 40% of the instructions have a CPI of 1, 25% have a CPI of 2, 20% have a CPI of 3 and 15% have a CPI of 5. Find the number of instructions per second if the machine is running at 900 MHz? 3. If 5 processors can run a program 2 times faster than a single processor, how much faster than a single processor can 10 processors run the same program? 4. If the base machine can run the 5 SPEC benchmarks in 1Os, 20s, 30s, 40s and 60s, whereas the target machine can run them in 5s, 1Os, 5s, 10s and 40s, respectively, what is the SPEC value for this scenario?
Convert the following 32-bit hexadecimal values to RISC-V instructions (use the register names, like a0) and express any numeric values or labels in decimal Hints: Review Figure B.1 (first figure in Appendix B). Notice that all the instruction formats have field (part) in common. That part can be used to determine the instruction’s format. Once the format is known, other parts and values can be identified. imm values are signed and could be negative! Some imm values are split up into parts in unusual orders and have to be re-assembled. Such imm values may have “unspecified” bits that should be assumed to be 0 a) 0x00A4F2B3 b) 0x00512423 c) 0xFE058CE3
