Reliability is nowadays starting to be considered as a key design parameter in processor design. However, whereas coding solutions such as parity or ECC are applied to protect large memory arrays, control logic and CAM memories are hard to protect this way. The issue queue is one of the most vulnerable structures in a processor, and hence specific techniques will soon be mandatory to protect it. This paper details a mechanism for detecting and correcting errors in the issue system logic of out-o...
