| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently, it has been getting inefficient to design microprocessors with worst-case margins because of increasing process and temperature variability. Thus, microarchitectural techniques which dynamically detect and recover from timing-errors have come to be researched. Previously, we have focused on timing-errors in register-file writing, and have proposed the technique named active WAB and passive WAB. In this paper, we will reduce the overhead of passive WAB. Focusing on physical registers which are never read, we propose ``pop on release'' and ``pop on flush'', and introduce them into passive WAB. Simulation result showed that the number of stall cycles and additional register reads are significantly reduced this modification. |
