Abstract
This paper presents a neural signal processing ASIC based on discrete wavelet transform (DWT). The recorded neural signals from 256 channels are analyzed by fast DWT algorithm with special ALUs, then, compressed by run-length encoders (RLE). The processed data are delivered through RF links and reconstructed in a host receiver. This design operates at 200 MHz clock with 2.5 V and was implemented with TSMC 0.25 mum technology. Recorded neural data test shows 1:89:3 (1.12%) compression rate and perfect in-band noise rejection
