DC-SIMD : Dynamic communication for SIMD processors
SIMD (single instruction multiple data)-type processors have been found very efficient in image processing applications, because their repetitive structure is able to exploit the huge amount of data-level parallelism in pixel-type operations, operating at a relatively low energy consumption rate. However, current SIMD architectures lack support for dynamic communication between processing elements, which is needed to efficiently map a set of non-linear algorithms. An architecture for dynamic communication support has been proposed, but this architecture needs large amounts of buffering to function properly. In this paper, three architectures supporting dynamic communication without the need of large amounts of buffering are presented, requiring 98% less buffer space. Cycle-true communication architecture simulators have been developed to accurately predict the performance of the different architectures. Simulations with several test algorithms have shown a performance improvement of...
