Dynamically Reconfigurable SIMD Architecture

Summary

A new SIMD architecture for vision chips has been designed, which features the function of clustering multiple PEs and that enables the hardware to be dynamically reconfigurable. This architecture performs non-local operations efficiently, which conventional SIMD processors are not good at.
