Abstract :
A FPGA design of time-domain convolutional interleaver in Chinese Digital Television Terrestrial Broadcasting (DTTB) system is proposed. Synchronous Dynamic Random Access Memory (SDRAM) is adopted in the design. Due to the large interleave-width, an overlarge interleaving unit is divided into some sub interleaving units. The result of the simulation is presented. Owing to the burst mode of SDRAM, the processing speed is lifted and the cost is cut down greatly.
