摘　　要：将FPGA应用在数字信号处理的主流技术DSP中是Altera推广的重要应用之一,本文依据Altera提出的基于FPGA的DSP解决方案,按照面向系统级和算法级的硬件设计思路,为语音信号处理领域中一项重要技术——"基音周期特征提取"实现DSP-IP核和执行架构的设计,并通过性能评价分析验证算法的DSP实现使整个系统在执行效率上的大幅提高。It is one of the most important applications to employ FPGA in ＂DSP＂, which is one of the mainstream technologies in the field of digital signal processing. This thesis employs the system-oriented and algorithm-oriented ideas to implement the design of DSP-IP Core and its execution architecture for an important technology !n speech signal processing——＂pitch feature abstraction＂ according to the FPGA-based DSP solutions supposed by Ahera. The performance analysis results show that DSP solutions of the algorithm make the great promotion of efficiency of the whole system.
