Homework Answers
E - None Commited
C - None Commited
A - None Commited
B - None Commited
F - Commit C, E
D - Commit C, E
The instructions are executed in this order hence the diagram follows-
IF is Instruction Fetch
ID is Instruction Decode
EX is Execution
MEM is Memory Operation
WB is Write Back
These are the steps in a superscalar CPU
Now, E executes first hence nothing is commited same goes for C, A, B as they're still in the pipeline
By the time F, D are executed E, C are commited.

AziTech is considering the design of a new CPU for its new model of computer systems for 2021. It is considering choosing between two (2) CPU (CPUA and CPUB) implementations based on their performance. Both CPU are expected to have the same instruction set architecture. CPUA has a clock cycle time of 60 ns and CPUB has a clock cycle time of 75 ns. The same number of a particular instruction type is expected to be executed on both CPUs...
