ABSTRACT:
An integrated CMOS circuit is disclosed for deinterleaving transmitted data packets. The circuit operates with a RAM buffer that is no larger than a block of interleaved data. An optimized addressing scheme is provided that minimizes on-chip hardware. The circuit provides an orderly initialization of the buffer, and a suitable emptying process during a channel change or other interruption of data flow.
