METHOD AND APPARATUS TO CREATE REGISTER WINDOWS FOR PARALLEL ITERATIONS TO ACHIEVE HIGH PERFORMANCE IN HW-SW CODESIGNED LOOP ACCELERATOR

An apparatus includes a register file and a binary translator to create a plurality of strands and a plurality of iteration windows, where each iteration window of the plurality of iteration windows is allocated a set of continuous registers of the register file. The apparatus further includes a buffer to store strand documentation for a strand from the plurality of strands, where the strand documentation for the strand is to include an indication of a current register base for the strand. The apparatus further includes an execution circuit to execute an instruction to update the current register base for the strand in the strand documentation for the strand based on a fixed step value and an iteration window size.
