Careful pipelining and scheduling has minimized the local storage requirement to tens of kB. The 40-nm CMOS test chip operates from 98 MHz at 0.9 V to 25 MHz at 0.5 V. The test chip processes 13 megapixels/s while consuming 17.8 mW at 98 MHz and 0.9 V, achieving significant energy reduction compared with software implementations on recent mobile processors. 收起
