该论文提出了一款384通道的在线尖峰分类(OSS)集成电路,采用无监督Geo-OSort聚类算法,实现了低复杂度、硬件高效的片上处理,解决了高密度神经记录系统中数据传输带宽和实时闭环应用的瓶颈。
neural-recording devices get denser and generate more data [1], on-chip and online neural-signal processing becomes crucial to reduce the data-transmission power and enable real-time closed-loop applications with minimum latency. Spike sorting (SS) is an important data-reduction technique that allows the classification of extracellularly recorded spikes into clusters representing the neuron sources. SS requires computationally intensive algorithms usually implemented offline in software [2]. However, to enable on-chip and online SS (OSS), a low-complexity and hardwareefficient algorithm is required to achieve minimal area, energy and latency, while maintaining comparable accuracy. Although several multi-channel OSS chips have been
