Abstract
A heterogeneous system for image processing was designed. The system consists of two layers with an array of DSPs in the low level layer and an array of PCs in the high level layer. The system resembles two stage multi-layers architecture. In the preprocessing phase, image data is delivered to the low level processors and operations are handled by using SPMD paradigm. The processed data is delivered to the high level processors where feature extraction and recognition tasks are performed. Apparently, the performance of this system is highly depended on communication mechanism used. The communication between two heterogenous processing layers is a critical design issue and is described in this paper. In our design, we have employed QuickRing. QuickRing provides a high transfer rate, 160 Mbytes/s, and supports multicast mode of data transmission that is suitable for broadcasting of data.
