Asynchronous SIMD: an architectural concept for high performance image processing

Traditional single-instruction multiple-data (SIMD) array processors have fallen out of favor for a long list of reasons. Most of these problems can be traced to the synchronous and monolithic nature of the array. The article lists the problems that derive from those characteristics and then proposes an asynchronous variation on the SIMD array that appears to have considerable potential for addressing the problems of SIMD while retaining its most attractive features. This architecture is presented as an interesting concept that is worth further exploration in the research community
