What is the role of control signals in a CPU?
Think about how instructions are executed.
What does the term 'external signals' refer to?
Consider what informs the CPU from memory or devices.
What is the main role of control signals in a CPU?
Remember their function.
True or False: External signals can influence the state transitions of a finite state machine.
Think about how orders from outside the CPU might affect internal processes.
Design a simple finite state machine for an instruction that loads data from memory. Identify the external and internal signals involved.
Draw out the state transitions involved to visualize the process.
Evaluate how system performance can be affected by the variability in response time of external signals.
Consider the implications of waiting cycles in a real-world processing task.
