Summary:PROBLEM TO BE SOLVED: To provide an encoder/decoder (CODEC) capable of accessing a block of video data with a reduced number of address calculations.SOLUTION: A device uses an innovative architecture in which functionality is partitioned between an embedded processor, a digital signal processor and dedicated hardware to achieve increased performance. The device comprises: a memory having linearly addressable storage units to store video data; and a programmable video direct memory access (VDMA) controller to retrieve video data from memory in response to a command specifying a multidimensional block of video data.
