Limitations of special-purpose instructions for similarity measurements in media SIMD extensions
CASES '06: Proceedings of the 2006 international conference on Compilers, architecture and synthesis for embedded systemsPages 293–303https://doi.org/10.1145/1176760.1176796Microprocessor vendors have provided special-purpose instructions such as psadbw and pdist to accelerate the sum-of-absolute differences (SAD) similarity measurement. The usefulness of these special-purpose instructions is limited except for the motion ...

Matrix register file and extended subwords: two techniques for embedded media processors
CF '05: Proceedings of the 2nd conference on Computing frontiersPages 171–179https://doi.org/10.1145/1062261.1062291In this paper we employ two techniques suitable for embedded media processors. The first technique, extended subwords, uses four extra bits for every byte in a media register. This allows many SIMD operations to be performed without overflow and avoids ...

A new look at exploiting data parallelism in embedded systems
CASES '03: Proceedings of the 2003 international conference on Compilers, architecture and synthesis for embedded systemsPages 159–169https://doi.org/10.1145/951710.951733This paper describes and evaluates three architectural methods for accomplishing data parallel computation in a programmable embedded system. Comparisons are made between the well-studied Very Long Instruction Word (VLIW) and Single Instruction Multiple ...
