- Abstract
- Implementation of recursive equations using parallel computer architecture has long been of interest because the dependency problem makes it difficult to achieve significant speed-up. In this paper, efficient implementation of recursive filtering equations on partitioned data-path SIMD (Single Instruction Multiple Data) processors is studied. Especially, three parallel computation techniques, which are the block filtering, recursive doubling, and multi-block filtering methods, are implemented and their performances are compared using a Pentium CPU based system. The performance evaluation result of the multi-block processing method on a scalable SIMD processor is also presented.
