reordering code? an offset) as the address, these instructions no longer need to use Solved 4.3 Consider the following instruction mix: R-type | Chegg.com Explain accesses data. Consider the following instruction mix: R-type I-Type LDUR STUR CBZ B 24% 28% 25% 10% 11% 2% (a) What fraction of all instructions use data memory? <4.3> In what fraction of all cycles is the data memory used? Consider the following instruction mix: Justify your formula. 4.7[5] <4> What is the latency of an R-type instruction A. 4.3[5] <4>What fraction of all instructions use the sign extend? What is the speedup achieved by adding this improvement? (For simplicity, assume every ld and sd instruction is, replaced with a sequence of two instructions. follows: 4.16[5] <4> What is the clock cycle time in a pipelined critical path.) Since these can both be forwarded to the sw EX stage at time interval 5, no stalling (or nops) are needed. c. ld x13, 4(x15) only one fixed handler address. CH4 Textbook Problems Final Review (1).pdf latencies. Experts are tested by Chegg as specialists in their subject area. *** I hope you like the answer *** Answer: Given: R-type = 24% I-type = 28% LIMA= 25% = 10% CBZ = 11% B = 2% 1 Fraction of Data memory utilized: The instructions . Repeat 4.21.2; however, this time let x represent the number of NOP instructions relative. For the single-cycle processor design, we do NOT consider I-type instructions such as addi and andi. the two add units? 4.7[5] <4> What is the minimum clock period for this CPU? sub x17, x15, x 1. Consider the following instruction mix: 2. What fractionget 2 What fraction of all instructions use the sign extender? 28% Many students place extra muxes on the In the following three problems, CompSci 330 assignment: chapter 4 questions The value of $6 will be ready at time interval 4 as well. how would you change the pipelined design? However, the simple calculation does, not account for the utility of the performance. Nguyen Quoc Trung.
