Optimo: A 65Nm 270Mhz 143.2Mw Programmable Spatial-Array-Processor With A Hierarchical Multi-Cast On-Chip Network For Solving Distributed Optimizations

This paper presents OPTIMO, a 65nm, 16-b, fully-programmable, spatial-array processor with 49-cores and a hierarchical multi-cast network for solving distributed optimizations. We demonstrate six template algorithms and their applications and measure a peak energy-efficiency of 0.279 TOPS/W.
