Abstract

In a normal, non-loop mode a uOp buffer receives and stores for dispatch the uOps generated by a decode stage based on a received instruction sequence. In response to detecting a loop in the instruction sequence, the uOp buffer is placed into a loop mode whereby, after the uOps associated with the loop have been stored at the uOp buffer, storage of further uOps at the buffer is suspended. To execute the loop, the uOp buffer repeatedly dispatches the uOps associated with the loop's instructions until the end condition of the loop is met and the uOp buffer exits the loop mode.
