4 cards from this section. Quick, good the night before a test.
What does the program counter do?
Think about what the CPU needs to know to fetch instructions.
What is clock grouping?
Consider how timing can optimize instruction fetches.
What does the program counter do in the instruction fetching process?
Think about what direction the CPU needs to go next.
True or False: Clock grouping optimizes the instruction fetching process by allowing all operations to occur at once.
Consider how dependency affects timing.
Design a hypothetical instruction fetch cycle for an instruction requiring both immediate and non-immediate addressing modes. Outline each micro-instruction step involved.
Think about how to alternate between direct data accesses and fetching from memory.
Create a detailed flowchart depicting the instruction fetching process illustrating clock grouping.
Consider how each step connects and where timing optimizations may occur.
