Abstract
Methods, apparatus, systems and articles of manufacture to compress data are disclosed. An example apparatus includes an off-chip memory to store data; a data slicer to split a dataset into a plurality of blocks of data; a data processor to select a first compression technique for a first block of the plurality of blocks of data based on first characteristics of the first block; and select a second compression technique for a second block of the plurality of blocks of data based on second characteristics of the second block; a first compressor to compress the first block using the first compression technique to generate a first compressed block of data; a second compressor to compress the second block using the second compression technique to generate a second compressed block of data; a header generator to generate a first header identifying the first compression technique and a second header identifying the second compression technique; and an interface to transmit the first compressed block of data with the first header and the second compressed block of data with the second header to be stored in the off chip memory.
