What is a pipelined processor?
- A pipelined processor allows multiple instructions to execute at once, andeach instruction uses a different functional unit in the datapath. This increases throughput, so programs can run faster. —One instruction can finish executing on every clock cycle, and simplerstages also lead to shorter cycle times.
What are the features of 8086?
- • 8086 is an enhanced version of 8085 designed by INTEL in 1976. • It is a 16 bit processor which has 16 data lines and 20 address lines. • It provides up to 1MB storage.
What is a pipelined datapath?
- The pipelined datapath combines ideas from the single and multicycleprocessors that we saw earlier. —It uses multiple memories and ALUs. —Instruction execution is split into several stages. Pipeline registers propagate data and control values to later stages.
Why do we divide instruction execution into multiple cycles in pipelining?
- In pipelining, we also divide instruction execution into multiple cycles. Information computed during one cycle may be needed in a later cycle.—The instruction read in the IF stage determines which registers arefetched in the ID stage, what constant is used for the EX stage, andwhat the destination register is for WB.
