Are you proposing a 32-issue processor instead of eight 4-issue cores? One problem with that is that most software doesn't have enough instruction-level parallelism to use such resources. Such a complex processor would also be likely to become bottlenecked on central control structures like the issue window (which can be solved with clustering, but then you're almost back to multicore). But check out EDGE/TRIPS/E2 for some ideas in this area. |
