Compiler-managed register file protection for energy-efficient soft error reduction

The register file is a critical component in a modern superscalar processor. It must be large enough to accommodate the results of all in-flight instructions. It must also have enough ports to allow simultaneous issue and writeback of many values each ...

For embedded systems, where neither energy nor reliability can be easily sacrificed, this paper presents an energy efficient soft error protection scheme for register files (RFs). Unlike previous approaches, the proposed method explicitly optimizes for ...

Most power reduction techniques have focused on gating the clock to unused functional units to minimize static power consumption, while system level optimizations have been used to deal with dynamic power consumption. Once these techniques are applied, ...
