Abstract
Embodiments of the present disclosure include a digital circuit and method for multi-stage compression. Digital data values are compressed using a multi-stage compression algorithm and stored in a memory. A decompression circuit receives the values and performs a partial decompression. The partially compressed values are provided to a processor, which performs the final decompression. In one embodiment, a vector of N length compressed values are decompressed using a first bit mask into two N length sets having non-zero values. The two N length sets are further decompressed using two M length bit masks into M length sparse vectors, each having non-zero values.
