A designer decides to add a fused multiply-add (FMA) instruction to our MIPS processor. The instruction does the following operation on registers: A=A*B+C. What type of instruction format can we use to encode this new instruction?
I, J, Need a new format or R

1 For a given processor bound workload the frequencies of instructions move (MOV), floating add (FADD), and floating multiply (FMUL), and the corresponding instruction run times, for a given processor are: FADD 10 300 Others 50 160 MOV Instruction Frequency 30 Time [nanosec] 100 FMUL 10 600 What is the MIPS indicator of this processor? Faster memory chips reduce the MOV time by 50%, and all other times by 20%. What is now the value of the MIPS indicator? The...

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.
