Flexible UDec ASIP Processor with Multimode Turbo Decoder

Channel decoding is a key feature of a wireless communication standard. It allows reliable data transfer targeting high throughput over unreliable communication channels. However, a channel coding techniques is typically associated to a variety of parameters and configuration options (frame size, communication channel, signal to noise ratio, etc) among channel decoding techniques, Turbo codes are frequently adopted in the recent wireless standards to reach a very low bit error rate (BER). Furthermore, the high through put requirement of emerging services imposes the efficient exploitation of different parallelism levels of the underlying algorithms supports several wireless communication standards and is integrated in a scalable and flexible multiprocessor platform, namely UDec.
