3 cards from this section. Quick, good the night before a test.
What is the purpose of the program counter?
Think about how the CPU knows which instruction to process next.
Explain immediate addressing in a single sentence.
Consider how data is represented directly in an instruction.
What is the function of the opcode in an instruction?
Remember, opcodes are crucial to defining actions within a CPU.
True or False: Indirect addressing mode uses an operand's value directly in instruction.
Think about how data is retrieved in this mode.
Assuming a CPU requires two memory locations for a single instruction involving an operation plus two operands, how would it retrieve the data? Outline the steps involved.
Consider the multiple bytes needed based on instruction size.
Given a multi-word instruction, describe how to implement it in a language of your choice and determine how it impacts performance.
Think about how slow-memory performance might play a role here.
