一种有效的WCDMA信道编解码任务调度方案研究

Task Manipulation Scenario Investigation of Channel Coding/Decoding Module in Slot- Based WCDMA Terminal

根据WCDMA多信道复用、高速率业务以及终端系统在功耗,性能,体积等方面的一系列要求,提出了一种基于时隙(slot)调度信道编解码模块中各子处理单元的方案,可使整个模块资源配置更加优化,执行效率更高。考虑到DSP处理器和大规模FPGA各自突出的性能特点,本文采用DSP和FPGA协同处理来实现整个方案。

According to WCDMA multi-channels multiplexing, high data rate operation and the requirements of power loss, performance and size in terminal system, a slot-based scenario is proposed to manipulate sub-processing units in channel coding/decoding module, by which the whole module resource configuration can be optimized and the higher operation efficiency can be achieved. Considering the respective prominent performance characteristics of DSP and large-scale FPGA, they will be cooperated to implement in the whole scenario.
