Instruction Cycle
It is defined as ·"the time required to complete the execution of an instruction". An instruction cycle may consist of no. of machine cycles. For 8085 an instruction cycle may consist one to five machine cycles.
T State’s
When a microprocessor executes an instruction, it performs several operations, controlled by the clock. Each operation may take multiple clock cycles. In microprocessor terms, "the sub-division ·of an operation, which equals to one clock period is called as T-state".
Machine Cycle
It is defined as "the time required to complete any operation, which is a sub-part of an instruction". The machine cycle may consist of several T-states. For 8085 a machine cycle may consist of three to six T-states depending upon which machine cycle operation is being carried out.
