The FPU (Floating Point Unit) writes the results to the floating point register file in
A. X1 execution state
B. X2 execution state
C. write back stage
D. none of the mentioned
Answer:A
The FPU (Floating Point Unit) writes the results to the floating point register file in
A. X1 execution state B. X2 execution state C. write back stage D. none of the mentioned
Explanation: In the two execution stages of X1 and X2, the floating point unit reads the data from the data cache and executes the floating point computation. In the “write back stage” of pipeline, the FPU (Floating Point Unit) writes the results to the floating point register file.
