INTRODUCTION The Burroughs Scientific Processor (BSP) is one of the first machines of its class to employ the features of single-bit error correction of memory data and instruc- tion retry. The system design embodies extensive error-detection capabilities that are the necessary foundations for effective retry. Additionally, all major data paths are protected with a modified Hamming code which provides single-bit error detection and correction and double-bit error detection. These features, coupled with the failure log capabilities, provide the scientific user and the Burroughs field engineer with state-of-the-art maintenance capabilities.
