path)
(c)The path from instruction [20-16] to Register ReadRegister2 (Not
on critical path)
(d)The path from Register ReadData2 to DM write data (Not on
critical path)

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.
