Abstract:
A matrix compression/decompression accelerator (MCA) system/method that coordinates lossless data compression (LDC) and lossless data decompression (LDD) transfers between an external data memory (EDM) and a local data memory (LDM) is disclosed. The system implements LDC using a 2D-to-1D transformation of 2D uncompressed data blocks (2DU) within LDM to generate 1D uncompressed data blocks (1DU). The 1DU is then compressed to generate a 1D compressed superblock (CSB) in LDM. This LDM CSB may then be written to EDM with a reduced number of EDM bus cycles. The system implements LDD using decompression of CSB data retrieved from EDM to generate a 1D decompressed data block (1DD) in LDM. A 1D-to-2D transformation is then applied to the LDM 1DD to generate a 2D decompressed data block (2DD) in LDM. This 2DD may then be operated on by a matrix compute engine (MCE) using a variety of function operators.

Claim (Index 11):
A matrix decompression accelerator system comprising:\n external data memory; local data memory; and data transfer processor, the data transfer processor is configured to transfer data between said external data memory and said local data memory; wherein the external data memory or the local data memory further comprise one or more compressed and uncompressed data fields, capable of being configured as a compressed superblock for transfer; wherein the local data memory stores a compression mode vector that contains information on the type of compression used for each of said uncompressed data fields within said compressed superblock that can be read by the data transfer processor; wherein the compressed superblock stored in said local data memory is decompressed by the data transfer processor to generate 1D decompressed data blocks based on the contents of said compression mode vector; wherein the 1D decompressed data blocks is stored in said local data memory by the data transfer processor; wherein the 1D decompressed data blocks is read from said local data memory by the data transfer processor; wherein the data transfer processor executes a 1D-to-2D transformation on said 1D decompressed data blocks contained in said local data memory to generate 2D decompressed data blocks; and wherein the data transfer processor stores the 2D decompressed data blocks in said local data memory.
