摘要
提出了一种低功耗传感器节点处理器，用于连续健康监测。将生物信号处理块集成到处理器中，支持压缩和加密。为了降低传输功耗和存储容量，提出了一种二次级生物信号压缩算法。并集成了AES-128数据加密数据路径，实现了用户隐私和身份验证。CR为8.4:1,PRD为0.87%，压缩率为6.4 Mbps。加密速率为1.6 Mbps，标准化性能为0.4b/cycle/k-gates，是目前相关工作中最高的。该处理器采用0.25 μ m CMOS工艺，在1V电源电压和1MHz工作频率下功耗为0.56 nJ/bit。
A low energy bio sensor node processor for continuous healthcare monitoring system
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.
