摘　　要：语音识别是当前研究热点之一,应用十分广泛。系统浮点运算量很大,所以采用浮点型DSP。文章主要研究以DSP处理器为核心的硬件系统,包括电源电路,复位电路,时钟电路,JTAG接口电路,外部存储电路和语音处理电路等,并对每个电路模块进行详细的阐述。该方案已经可以作为模板电路实现。Now, speech recognition is one of the hot research topics and is used widely. Due to the huge amount of floating-point calculations of the system, a floating DSP is utilized. The primary object of this essay is to study the hardware system which is based on the DSP, including power circuits, reset circuit, clock circuit, JTAG interface circuit, external storage circuit and speech processing circuit, etc. The detailed function of every module circuit is elaborated. The scheme has been implemented as a template circuit.
