Purpose of using Instruction Queue

Purpose of using Instruction Queue: BIU contains an instruction queue. When the EU executes instructions, the BIU gets up to 6 bytes of the next instruction and stores them in the instruction queue and this process is called instruction prefetch. This is a process to speed up the processor. A subtle advantage of instruction queue …
