what will be answer?

do we count 10 cycles for mov r1,(r2) or only 5 cycles?

basically ,confusion is that should i count memory to MBR as one memory register operation.

by term memory to register transfer do they mean ,memory to general purpose register(registers which are provided to a  programmer) only?

I1: 2*4 + 5 (Fetch & Decode unit depends on instruction word, not execute unit)

I2: 2*4 + 5

I3: 4 + 3

I4: 4 + 2

I5: 4*2 + 2

I6: 4

Total execution time = 53 cycles
