Abstract:
1. A Reed-Solomon (RS) decoding engine in a memory architecture of a media access control (MAC) de-interleaver random access memory (RAM) that increases a throughput of RS decoders in a MediaFLO™ (forward link only) receiver, the architecture comprising: parallel RS decoder cores comprising a RS decoder that decodes received data, wherein the number of parallel RS decoders equals a ceiling 16 ms/(122*floor (b/122/6)*r*t), wherein b is the size of a de-interleaver RAM in bytes, t is a clock period, r is a RS decoder core throughput in clock cycles per codeword, 16 is a size of a RS codeword, and 122 is the number of codewords in one error control block (ECB), wherein said number of codewords is equal to the number of bytes in one MAC packet; and a single port RAM for accessing said de-interleaver RAM.
