A 100 GOPS In-vehicle Vision Processor for Pre-crash Safety Systems Based on a Ring Connected 128 4-Way VLIW Processing Elements

摘要

A 100GOPS vision processor LSI (IMAPCAR) for in-vehicle image recognition which consumes less than 2 watts of power has been developed. 128 of 4-Way VLIW with MAC (multiply add accumulation) processor elements (PE) to which data are assigned efficiently by DMA companion scaling capability, has achieved high performance in low cost. Compared with a previous design, performance for major vision tasks has been improved by a factor of 2.5 while 50% of power is reduced.
