What are the organizational attributes?

The general design of it’s CPU, main memory, IO subsystem

The interconnections of the different functional units

The computer’s instruction set

Which is true about Control Unit (CU)?

Responsible for the sequence of operations to be performed.

It sends control signals to the other units of the computer for them to work.

It fetches program instruction one by one from the main memory, decodes their op-codes, & sends control signals to the other units of the computer system

It does all the computing of the computer whether mathematical or logical operations.

What are the CPU Registers?

General Purpose Registers (GPRs)

Registers of the ALU circuitry that serves as the working space while the data is being manipulated with the memory being accessed.

General Purpose Registers (GPRs)

Register that holds the address of the memory location to be accessed.

General Purpose Registers (GPRs)

Register that holds the address of the next instruction to be executed.

General Purpose Registers (GPRs)

Register that holds the content of the memory location read or where the result is to be stored.

General Purpose Registers (GPRs)

Which is true about BUSES?

The lines interconnecting the different functional units of the computer which allows the flow of data and information.

The passageway of data, addresses, and control signals.

Produces the sequence of the control signal necessary to execute the instruction.

F/E CYCLE (Fetch Phase)

Fetch the instruction from the memory.

Store the result to the memory/register.

Fetch the operand/s from the memory/register.

Execute Phase of F/E CYCLE

Fetch the operand/s from the memory/register.

Store the result to the memory/register.

Fetch the instruction from the memory.

TYPES OF PROGRAM INSTRUCTIONS

Register - Memory/Memory - Register Instructions

Instructions involved only register for both source and destination operands.

Register - Register Instruction

Register -Memory/Memory - Register Instruction
