Interleaver for digital signal decoding device, has addressing device to transmit, at each instant of clock, reading and writing instructions respectively to two RAMs, such that at each instant, data is written/read from each RAM

摘要

The interleaver has two random access memories (RAMs) (10, 11) to store data, and an addressing device (100) connected to respective address inputs of the RAMs. The device is arranged to transmit, at each instant of a clock, a reading instruction to one of the RAMs and a writing instruction to the other RAM, such that data is written in/read from each RAM, at each instant. An independent claim is also included for a digital signal decoding device having an interleaver and a decoder.
