A MIMD based multiprocessor architecture for real-time image processing suitable for a monolithic redundant realization

A novel MIMD (multiple instruction multiple data) based multiprocessor architecture consisting of multiple processing elements (PE) has been developed for real-time image processing. Each PE contains an arithmetic processing unit adapted to convolution-like low-level operations and a high-level and control processor. A high-speed random access to local image data is provided by two local input memories and an I/O and feedback unit. This architecture has a high regularity at the task level which is suitable for a WSI (wafer scale integration) implementation. The main parts of a PE have been realized as VLSI test chips providing a computational rate of up to 400 MOPS for one PE
