In computer science, instruction pipelining is a technique for implementing instruction-level parallelism within a single processor. Pipelining attempts to keep every part of the processor busy with some instruction by dividing incoming instructions into a series of sequential steps (the eponymous pipeline) performed by different processor units with different parts of instructions processed. Besides, the 8085 microprocessor has a 16-bit address bus, whereas the 8086 microprocessor has 20-bit address bus. Data bus. Also, 8085 has an 8-bit data bus while 8086 has a16-bit address bus. Pipelining. Moreover, the 8085 microprocessor does not support pipelining, whereas the 8086 microprocessor supports pipelining Instruction pipelining is a technique used in the design of modern microprocessors, microcontrollers and CPUs to increase their instruction throughput (the number of instructions that can be executed in a unit of time).. The main idea is to divide (termed split) the processing of a CPU instruction, as defined by the instruction microcode, into a series of independent steps of micro.
