What is the purpose of control signals in a CPU?
Think about how a conductor leads an orchestra.
Define a finite state machine.
Focus on the 'state' aspect in your definition.
What do control signals do in the CPU?
Think about what guides the CPU's activities.
True or False: Hardwired control units are more flexible than microprogrammed units.
Consider the nature of hardwired circuits.
Design a FSM for a simple CPU instruction set that handles addition and subtraction. Include the required states and transitions based on hypothetical opcodes.
Consider all steps involved in both operations and how they differ.
Evaluate the trade-offs between speed and flexibility in hardwired versus microprogrammed control units. Provide examples of scenarios where one might be preferred over the other.
Reflect on specific applications that benefit from speed or flexibility.
