Some ISA’s provide an instruction (often called NOP, for No
Operation) that simply does nothing. Like any other instruction, it
is fetched, decoded, and executed, except that the execution itself
does nothing.
a. Give one use case for a NOP instruction : to insert
delays
b. Say RISCV does not provide a NOP opcode. How can we simulate
one with the existing instruction set? Provide the machine code for
this instruction.
