Techniques for compressing neural signals are disclosed herein. The neural signal compression techniques can include lossless compression, lossy compression, binned spike compression, and spike-band power compression. Lossless compression can compress neural signals using a difference predictor to encode compressed neural signals via binary and unary coding. Lossy compression can compress neural signals using quantized wavelet transforms to generate an encoded bit-stream of compressed neural signals. Binned spike and spike-band power compression can leverage the sparse nature of neural signals to threshold the neural signals for generating an appended bit-stream of compressed neural signals.

Neural signal compression for brain-machine interface

A method includes receiving a block comprising pixels; encoding the pixels by: arranging the pixels in a sequence; generating a delta encoding of the pixels, the delta encoding comprising (a) a base value and (b) delta values having non-zero delta values and zero delta values, each delta value representing a difference between a corresponding pixel in the sequence and a previous pixel in the sequence; generating a symbol mask indicating whether each of the delta values is zero or non-zero; determining, based on magnitudes of the non-zero delta values, a symbol width for encoding each of the non-zero delta values; generating a sequence of symbols that respectively encode the non-zero delta values using the symbol width; generating a compression of the block by collating the symbol mask, the symbol width, and the sequence of symbols.
