Question

the number of timing states for sap 1

Answer 1

Answer:

please put me brainly list for answer

Explanation:

SAP1 has six T-states (three fetch and three execute cycles) reserved for each instruction. Not all instructions require all the six T-states for execution. The unused T- state is marked as No Operation (NOP) cycle. Each T-state is called a machine cycle for SAP1. A ring counter is used to generate a T-state at every falling edge of clock pulse. The ring counter output is reset after the 6th T-state.
