A 100 GOPS in-vehicle vision processor for pre-crash safety systems based on a ring connected 128 4-Way VLIW processing elements

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.
