Image processing performance evaluation for DSP based parallel computers with distributed frame buffers

Performance evaluation criteria are presented to provide a useful tool for comparing current digital signal processing (DSP)-based parallel machines used in image processing (IP) applications. Additionally, these criteria can be considered as a step toward a unified computation model for IP which may influence the design of future parallel architectures using distributed frame buffers. As an example, it is shown how to determine the criteria for a parallel machine with a mesh connected architecture and 2-D interleaving scheme. Benchmarks are derived as a function of key architectural parameters (e.g. the number of processors) and image parameters. The use of the criteria in determining task performance is explained.<>
