A loop buffer is a small, very-high-speed memory maintained by the instruction fetch stage of the pipeline and containing the n most recently fetched instructions in sequence.
Loop buffer function is to maintained the pipeline IF stage. It mean when the some branch of instruction will taken, the program will check the loop buffer first to see the instruction if it existing or not, then if the instruction is not exist in the loop buffer, then we must to get it.
The loop buffer will keep the information data and their control into the shared memory. So it make efficiency of the program higher than without the loop buffer.
