How many time does the control unit refers to memory when it fetches and executesan indirect addressing mode instruction if the instruction is,a. A computational type requiring an operand from memoryb. A branch type

The control unit is central to the operation of the CPU. Describe the control unit’s role in the execution of machine code statements.

A computer has a main memory with 16 bits per word and a CPU with16 general purpose registers. The instruction set consists of10 differentoperations and each instruction has two operands. Each operandidentifies an immediate value, a register value, or a memory location.The processor can access memory using 6-bit addresses. Specify theinstruction fonnat and the number of bits in each field if the instructionis stored in one word of memory.
