Multimedia Performance Analysis of a Descriptor Computer

摘要

The rapid moving of computing into multimedia leads computers to include special instructions to support multimedia operations, including those with RISC architectures [5,6]. Multimedia performance now becomes a pseudo-benchmark for modern processors. This paper presents such benchmark in HISC, which stands for High-level Instruction Set Computer [1,2]. HISC is a general-purpose descriptor computer of high-level operation instructions with variable length operands, together with associated system attributes for the operands. The operands of HISC can be variable lengths and vectors. Therefore these characteristics are destinated to support multimedia applications.
