An SDRAM convolutional interleaver with two paths. Symbols are assigned to a given one of the two paths, then are sorted to minimize (to one) a number of breaks in a sequential Interleaver write address. After sorting, the symbols are stored staggered in SRAM and burst written to SDRAM. Before writing to SDRAM, data is accumulated for four symbols at a time, and the data is written four symbols wide to optimize SDRAM access time. 8 bit symbols are written 32 bits at a time to SDRAM.
