摘要

具有集成谐振时钟发生器的绝热电荷回收混合信号阵列每兆瓦功率可提供175 GMACS(每秒乘法和累加)吞吐量,比用CMOS驱动器取代谐振线驱动器时产生的动态功率提高10倍。3-T CID/DRAM单元提供非破坏性的1b-1b乘法累积,集成量化器产生8位输出,最坏情况下不匹配+/- 1 LSB。这个256乘以512的四象限阵列被嵌入到一个处理器中,用于基于模板的人脸检测

175 GMACS/mW Charge-Mode Adiabatic Mixed-Signal Array Processor
An adiabatic charge-recycling mixed-signal array with integrated resonant clock generator delivers 175 GMACS (multiply-and-accumulates per second) throughput for every mW of power, a ten-fold improvement over the dynamic power incurred when resonant line drivers are replaced with CMOS drivers. The 3-T CID/DRAM cell provides non-destructive 1b-1b multiply accumulation, and integrated quantizers yield 8-bit outputs with +/- 1 LSB worst-case mismatch. The 256 times 512 four-quadrant array is embedded in a processor for template-based face detection
