Abstract :
A description is given of alternative implementations of such circuits and various ways in which they can be connected in VLSI modules. The authors also describe possible performance enhancements through the use of a technique, called micro rollback, which allows error detection to be performed in parallel with intermodule communication. As a concrete example, they present area and performance measurements of alternative microarchitectures and circuits that can be used to add detection and correction to a VLSI RISC processor they are implementing
