The methods of digital speech signal short-time processing with FPGA are presented in this paper.
本文围绕如何用FPGA实现语音信号常用特征提取,介绍了信号短时处理的概念和Altera的DSP Builder开发工具,并以短时能量和短时平均过零率为例,介绍了具体实现方法,给出了仿真结果,在EP1K100上验证了方法的正确性。
Based on Open-fund system project,the paper expounded two aspects of fund system′s DataProcess:DayBeginProcess and DayEndProcess,and at the same time the part of DataProcess′s pseudocode has been listed.
随着基金业务日处理量的加大,待处理的数据规模也随之剧增,在开放式基金系统工程的基础上,阐述了基金系统数据处理模块的两个方面:日初处理和日终处理功能,同时给出了部分数据处理的伪码。
