The need for processing speed in digital imaging and multidimensional signal processing seems to grow ever faster as more and more power hungry applications find their way into scientific and engineering applications. In this paper we evaluate the performance of a high-speed parallel system aiming at real time applications. The parallel system utilises a 2-D hybrid decomposition algorithm that eliminates the problem of overlapping segments in the block convolution and the boundary conditions when paralleling a 2-D filter algorithm. Finally the implementation on parallel SHARC DSPs is investigated and some examples are given
