High throughput interleaver / deinterleaver |
摘要 |
Systems and methods for performing high-speed multi-channel forward error correction using external DDR SDRAM is provided. According to one exemplary aspect, an interleaver/deinterleaver performs both read and write accesses to the DDR SDRAM that are burst-oriented by hiding active and precharge cycles in order to achieve high data rate operations. The interleaver/deinterleaver accesses data in the DDR SDRAM as read blocks and write blocks. Each block includes two data sequences. Each data sequence further includes a predetermined number of data words to be interleaved/deinterleaved. The PRECHARGE and ACTIVE command for one data sequence is issued when a preceding data sequence is being processed. Data in one read/write data sequence has the same row address within the same bank of the DDR SDRAM.
