摘要
采用数字信号处理器DSP设计了数字声级计的硬件系统,阐述了数字声级计设计原理及系统设计方案,对组成系统的各芯片的功能进行了详细说明,并阐明了如何利用它们实现ADC接口设计、存储器接口设计和电源设计。调试结果表明实验系统实现了预定的功能。
This paper presents the hardware design of the digital sound meter based on the digital signal processor（DSP）. It elaborates on the design principles and implementation of the digital sound meter, the functions of chips used in the system, and how to perform the designs for the interface between DSP and ADC, the interface between DSP and memory and the power supply by these chips. Tested results show that the experimental system has fulfilled the expected functions.
