Suppose the times required by each of the functional units of a MIPS processor to do their work are: Instruction Memory: 400 ps Data Memory: 400 ps ALU: 300 ps Register file: 200 ps lgnoring the overhead introduced by the pipeline registers, what is the maximum speedup achieved by the pipelined processor with fetch, decode, execute, memory and write back stages vis-a-vis the single-cycle processor? Give your answer to two decimal places.
Question 1 Figure 1 shows a datapath for R-type instructions which consits of a register file and an arithmetic logic unit (ALU). These instructions are also known as aritmetic-logical- instructions since they perform aritmetic or logical operations. The register file contains all the registers and provides two read ports and one write port. The register file always provides the contents of the registers corresponding to the read register inputs on the outputs, while the writes must be explicitly controlled with...

Modify the circuit to support a MFCC instruction. MFCC Rd instruction: Move From Condition Codes MFCC copies into the four rightmost bits of Rd the values of the ALU signals Carry (C), Overflow (O), Zero (Z) and Negative (N) as they were set by the previous R- type instruction. The remaining 28 bits of Rd are set to zero. Describe the changes and additions needed for the single-cycle MIPS processor datapath and control to support this instruction. Hints: 1) MFCC...
