Review request for Default, Ali Saidi, Gabe Black, Steve Reinhardt, and Nathan Binkert. Summary ------- inorder: add a fetch buffer to fetch unit Give fetch unit it's own parameterizable fetch buffer to read from. Very inefficient (architecturally and in simulation) to continually fetch at the granularity of the wordsize. As expected, the number of fetch memory requests drops dramatically Diffs ----- src/cpu/inorder/InOrderCPU.py 31a04e5ac4be src/cpu/inorder/resources/cache_unit.hh 31a04e5ac4be src/cpu/inorder/resources/cache_unit.cc 31a04e5ac4be src/cpu/inorder/resources/fetch_unit.hh PRE-CREATION src/cpu/inorder/resources/fetch_unit.cc PRE-CREATION Diff: http://reviews.m5sim.org/r/448/diff Testing ------- Thanks, Korey
