    The microprocessor has made it possible for a standard complex function to be employed in a broad range of applications that extends the applicability of large-scale integration (LSI) to many situations that could not support special chip designs. This in turn has freed the technology from previous restrictions to evolve in directions appropriate for microprocessors and associated LSI functions. T... View full abstract»

    Triple-modular redundancy (TMR) is a classical technique for improving the reliability of digital systems. However, applying TMR to microcomputer systems may not improve overall system reliability because voter circuits may contribute as much to system unreliability as the microprocessors themselves. We examine the issues that affect the effectiveness of TMR for transient recovery and the reliabil... View full abstract»

    For some time now, the notion that "an algorithm is an algorithm" has been emphasized in digital system design. In approaching such design problems, the question of hardware versus software implementation of the algorithm should be left to the last. In fact, such approaches have not been viable until the advent of the microprocessor, and software design has seemingly gone its own way independently... View full abstract»
