Abstract
A MPE-FEC memory chip and method for use in a DVB-H receiver, wherein the memory chip comprises a TS demux; a RS decoder; a system bus; and a RAM unit adapted to simultaneously interface to the TS demux, the RS decoder, and the system bus through time-multiplexing, wherein the RAM unit is adapted to (i) access multiple-words per clock cycle, and (ii) cache write and read accesses to reduce memory access from the TS demux and the system bus, and wherein the RAM unit is adapted to be clocked at a speed higher than an interfacing data-path to increase an effective throughput of the RAM unit. The RAM unit may comprise multiple RAM sub units, wherein while a first RAM sub unit is clock gated, the remaining multiple RAM sub units are accessible.
