Abstract:

This paper presents the Alpha EV8 conditional branch predictor. The Alpha EV8 microprocessor project, canceled in June 2001 in a late phase of development, envisioned an aggressive 8-wide issue out-of-order superscalar microarchitecture featuring a very deep pipeline and simultaneous multithreading. Performance of such a processor is highly dependent on the accuracy of its branch predictor and consequently a very large silicon area was devoted to branch prediction on EV8. The Alpha EV8 branch predictor relies on global history and features a total of 352 Kbits.
