  • Hidden fault bit apparatus for a self-organizing digital processor system
    Patent number: 4837683
    Abstract: A hidden fault bit apparatus for a self-organizing digital processor system utilizing a single bit of non-volatile memory to store a hidden fault bit in each digital processor unit of the system. The hidden fault bit indicates that the digital processor which contains it, is believed to contain a hidden fault and therefore, should not participate in the self-organization process.

  • Precision rounding in a floating point arithmetic unit
    Patent number: 4758972
    Abstract: A floating point computation unit having an arithmetic unit employing two guard digits for preserving information needed for rounding and an indicator generator for providing an indicator signal to a precision rounding apparatus. The indicator generator detects any digits beyond the guard digits of a shifted operand instead of waiting to detect such digits in the mantissa produced by an add or subtract cycle. The indicator generator comprises a priority encoder network coupled to a comparator for determining whether or not the least significant digits beyond the guard digits of the shifted mantissa are all zeros.
