Structure reconfigurability of the CNNUC3 for robust template operation
(Institute of Electrical and Electronics Engineers, 2000)
We demonstrate the importance of the reconfigurability of a 64/spl times/64 cells size CNN-UM chip. As we show, in such a high complexity mixed-signal VLSI circuit the switch and internal reference level reconfigurability ...
