Abstract
An apparatus includes a first memory interface circuit, a second memory interface circuit, and a compression circuit coupled between the first memory interface circuit and the second memory interface circuit. The compression circuit may be configured to receive a coding block of data via the first memory interface circuit, generate a reduced size representation of the coding block, and write the reduced size representation of the coding block to an external memory using the second memory interface circuit. The reduced size representation of said coding block generally comprises a first bit map, a second bit map, and zero or more non-zero values.
