Parallel Bit Stream Technology as a Foundation for XML Parsing Performance

Abstract

By first transforming the octets (bytes) of XML texts into eight parallel bit streams, the SIMD features of commodity processors can be exploited for parallel processing of blocks of 128 input bytes at a time. Established transcoding and parsing techniques are reviewed followed by new techniques including parsing with bitstream addition. Further opportunities are discussed in light of expected advances in CPU architecture and compiler technology. Implications for various APIs and information models are presented as well opportunities for collaborative open-source development.
