TC4300: China Multimedia Mobile Broadcasting (CMMB) LDPC decoder

TC4300 is a LDPC decoder designed for China Multimedia Mobile Broadcasting (CMMB) specifications. The Core is a stand-alone module, with no external memory needs. It is available for mainstream FPGA or ASIC device targets. Two throughput levels are proposed (*):

low-complexity Core : 75 Mbps
high-throughput Core : 150 Mbps

(*) Throughput depends on the selected device and vary with the number of iterations.
