Note, the total ++ # use of U0, and the total use of L0 (after attending to the stores). ++ # which is part of the reason why.... ++ # ++ # This is a great schedule for the d_cache, a poor schedule for the ++ # b_cache. The lockup on U0 means that any stall can't be recovered ++ # from. Consider a ldl in L1. say that load gets stalled because it ++ # collides with a fill from the b_Cache. On the next cycle, this load ++ # gets priority. If first looks at L0, and goes there. The instruction ++ # we intended for L0 gets to look at L1, which is NOT where we want ++ # it. It either stalls 1, because it can't go in L0, or goes there, and ++ # causes a further instruction to stall. ++ # ++ # So for b_cache, we're likely going to want to put one or more cycles ++ # back into the code! And, of course, put in prefetches. For the ++ # accumulator, flds, intent to modify. For the fmuldiplier, you might ++ # want ldl, evict next, if you're not wanting to use it again soon. Use ++ # 256 ahead of present pointer value. At a place where we have an mt ++ # followed by a bookkeeping, put the bookkeeping in upper, and the ++ # prefetch into lower. ++ # ++ # Note, the usage of physical registers per cycle is smoothed off, as ++ # much as possible. ++ # ++ # Note, the ldl's and stl's are at the end of the quadpacks. note, we'd ++ # like not to have a ldl or stl to preceded a conditional branch in a ++ # quadpack.

Note, the total ++ # use of U0, and the total use of L0 (after attending to the stores). ++ # which is part of the reason why.... ++ # ++ # This is a great schedule for the d_cache, a poor schedule for the ++ # b_cache. The lockup on U0 means that any stall can't be recovered ++ # from. Consider a ldl in L1. say that load gets stalled because it ++ # collides with a fill from the b_Cache. On the next cycle, this load ++ # gets priority. If first looks at L0, and goes there. The instruction ++ # we intended for L0 gets to look at L1, which is NOT where we want ++ # it. It either stalls 1, because it can't go in L0, or goes there, and ++ # causes a further instruction to stall. ++ # ++ # So for b_cache, we're likely going to want to put one or more cycles ++ # back into the code! And, of course, put in prefetches. For the ++ # accumulator, flds, intent to modify. For the fmuldiplier, you might ++ # want ldl, evict next, if you're not wanting to use it again soon. Use ++ # 256 ahead of present pointer value. At a place where we have an mt ++ # followed by a bookkeeping, put the bookkeeping in upper, and the ++ # prefetch into lower. ++ # ++ # Note, the usage of physical registers per cycle is smoothed off, as ++ # much as possible. ++ # ++ # Note, the ldl's and stl's are at the end of the quadpacks. note, we'd ++ # like not to have a ldl or stl to preceded a conditional branch in a ++ # quadpack.
