Abstract(in English) | Future excessive thinner process rules raises fault risk from defects and diffused faults. High speed and area effective fault-tolerant execution stage is difficult to implement because Functional Units (FU) do not have highly regulared structure. It is difficult to meet them by using a simple duplication of these FUs. We propose Heterogeneous Functional Units (HFU), which uses the combination of fast Functional Units (FU) and fault-tolerant FUs. HFU improves high speed performance for area effective fault-tolerant execution stage. By using HFU, area effective fault-tolerant execution stage is able to have high speed performance. Simulation result from SPEC2000 benchmarks shows that HFU has 99%, 94.2% speed performance compared to the simple fast execution stage, that is faster than 84.0% speed performance of the simple fault-tolerant execution stage. |
