摘要

本文介绍了在ADI TS201 TigerSHARC DSP上实现3GPP turbo解码器的一种高效软件实现方法。turbo解码器基于滑动窗口Log-MAP算法实现，并利用TS201 DSP的子字并行性和单指令多数据(SIMD)架构来实现以前只能在硬件上实现的高数据速率(约6 Mbps)。

An efficient implementation of turbo decoder on ADI TIGERSHARC TS201 DSP

This paper describes an efficient software implementation of the 3GPP turbo decoder on the ADI TS201 TigerSHARC DSP. The turbo decoder is implemented based on the sliding window Log-MAP algorithm and exploits the sub-word parallelism and single instruction multiple data (SIMD) architecture of the TS201 DSP to achieve high data rates (around 6 Mbps) that were previously achievable only in hardware.
