Abstract
A signal processing system includes a compression encoder 16 for compressing an input block of data samples including a plurality of sub-blocks, each sub-block including an array of data samples, into a block of compressed data. A sequencer 14' accesses the data samples of the input block to be passed to the compression encoder 16 with the sub-blocks being accessed in a predetermined first order and the data samples within each sub-block being accessed in a predetermined pseudo-random order such that successively accessed locations in the array of samples for a sub-block are scattered throughout that sub-block. The pseudo random accessing sequence enables occupancy of a buffer 73 for the compressed data block to be linearised. The sequencer can include a counter 62, the output of which addresses a look-up table 65 for generating the pseudo-random sequence in a repeatable manner.
