Abstract
A low energy sensor node processor is proposed for continuous healthcare monitoring application. The bio signal processing block is integrated into the processor to support the compression and the encryption. A quadratic level bio signal compression algorithm is proposed to reduce the transmission power consumption and the memory capacity. And the AES-128 data encryption datapath is integrated for user privacy and authentication. The CR is 8.4:1, the PRD is 0.897% and the compression rate is 6.4 Mbps. The encryption rate is 1.6 Mbps and the normalized performance is 0.4b/cycle/k-gates which is the highest value compared to the related works. The proposed processor consumes 0.56 nJ/bit at 1V supply voltage with 1MHz operating frequency in 0.25-mum CMOS process.
