Evaluation of the Turbo-decoder Coprocessor on a TMS320C64x Digital Signal Processor
One technique that is used to reduce the errors brought upon signals, when transmitted over noisy channels, is error control coding. One type of such coding, which has a good performance, is turbo coding. In some of the TMS320C64xTM digital signal processors there is a built in coprocessor that perf...
