An architecture of multi-DSP system and development environment for two-dimensional digital signal processing

A multi-DSP (digital signal processor) system which attempts to investigate algorithms for real-time digital signal processing is presented. A parallel digital filtering algorithm and a development environment are also described. It is found that the multi-DSP system has significantly higher computation performance than an engineering workstation. However, since the multi-DSP system requires significant data transfer capability, to achieve total higher performance, the bandwidth of the communication network between the workstation and the multi-DSP system must be improved
