Tile-based interleaving or de-interleaving using a burst-mode DRAM

摘要: A de-interleaving method for row-column interleaved data blocks comprises two DRAM access steps, each step operating on part of the block to re-order data. Data items are first read from input buffer 102 according a non-linear sequence addresses and written DRAM. The then bursts linear addresses, which makes efficient use interface, back on-chip memory write addresses. Crossing page boundaries is reduced. technique may be used in OFDM DVB-T2 systems processing real-time streams. an SDRAM, DDR or burst interleaving de-interleaving. .
