Abstract :
SLD(Silent Large Datapath)-1 is a prototype accelerator for media processing consisting of a large Processing Element (PE) array which includes 24bit 8 × 8 PEs with combinatorial circuits and a small micro-controller for data memory access. It was fabricated in 2.1mm × 4.2mm 65 nm CMOS, and achieves 1.356GOPS/11mW sustained performance by reducing overhead of clock tree and the benefit of voltage scaling.
