Paper Abstract
Parallel hardware becomes a commonly used approach to satisfy the intensive computation demands of computer vision
systems. A multiprocessor architecture based on hypercube interconnecting digital signal processors (DSPs) is described
to exploit the temporal and spatial parallelism. This paper presents a parallel implementation of low level vision algorithms
designed on multi-DSP system. The convolution operation has been parallelized by using redundant boundary
partitioning. Performance of the parallel convolution operation is investigated by varying the image size, mask size and
the number of processors. Experimental results show that the speedup is close to the ideal value. However, it can be
found that the loading imbalance of processor can significantly affect the computation time and speedup of the multi-
DSP system.
