基于定点DSP的自适应线谱增强系统设计

Design ALE system based on fixed-point DSP

以TI公司的TMS320VC5416定点数字处理芯片为核心,设计了包括采样时钟、输入转换、数据处理、输出转换等完整的一套自适应线谱增强处理系统。利用此芯片针对数据处理的专用指令,很好地消除了自适应过程中的截尾误差,大大提高了处理精度和自适应过程的稳定性;利用此系列芯片的高速处理能力、丰富的接口及各种片上外设,提高了整个系统的稳定性、吞吐能力和处理速度。最后,给出了实验结果及结论。

Based on Texas Instruments Incorporated＇s fixed-point DSP TMS320VC5416,designs a integrity ALE system includeds sample clock,input convert,data process,output convert etc.Uses chip instruction which special design for digital signal process, eliminates truncation error in adaptive process,and enhances process precision and adaptive stabilization greatly.Makes use of high process speed,lot of on-chip peripherals and interface of this chip,increases system throughput,stability and process speed. Finally,provides experimental result and conclusion.
