Abstract
A system and method for increasing the throughput of a RS decoder in MediaFLO™ receivers. A MAC de-interleaver RAM architecture allowing operation of parallel RS decoders comprises of four equal portioned memory banks, a codeword buffer for data correction, and a higher bit width RAM. The method of increasing throughput of RS decoder by minimizing RAM access and clock frequency includes increasing the bit width of the de-interleaver RAM, using parallel RS decoder cores for decoding received data, partitioning a 4-bank RAM and ECB allocation scheme, and correcting the data using intermediate buffers. The architecture enables on-chip implementation of the MAC de-interleaver RAM and RS decoders with reduced power consumption and provide higher RS decoder throughput.
