An additional stage for a Low Voltage Lazzaro’s Winner Take All (WTA) circuit is introduced. It allows lowering the voltage supply requirements so that it can be functional in fine line CMOS technology. Electrical measurements of a prototype in CMOS 0.5μm technology verify the operation of the WTA circuit with VDD = 1.5V. Simulations in PSpice and stability issues are presented as well.

This paper explores the role of branch predictor organization in power/energy/performance tradeoffs for processor design. We find that as a general rule, to reduce overall energy consumption in the processor it is worthwhile to spend more power in the branch predictor if this results in more accurate predictions that improve running time. Two techniques, however, provide substantial reductions ...

The coded aperture snapshot spectral imaging (CASSI) architecture has been employed widely for capturing hyperspectral video. Despite allowing concurrent capture of hyperspectral video, spatial modulation in CASSI sacrifices image resolution significantly while reconstructing spectral projection via sparse sampling. Several multiview alternatives have been proposed to handle this low spatial re...
