The 8086 architecture has a six-byte prefetch instruction pipeline, while the 8088 has a four-byte prefetch. As the Execution Unit is executing the current instruction, the bus interface unit reads up to six (or four) bytes of opcodes in advance from the memory. See more Fetching the instruction opcodes from program memory well in advance is known as prefetching and it is served by using prefetch input queue (PIQ).The pre-fetched instructions are stored in data structure - namely a See more The processor executes a program by fetching the instructions from memory and executing them. Usually the processor execution speed is much faster than the memory access … See more Processors implementing the instruction queue prefetch algorithm are rather technically advanced.
