【摘要】 介绍了多频互控的概念,提出了采用廉价的TMS320VC5402DSP来实现30/32路多频互控的方法,并阐述了实现过程中的几个关键问题。该方案是代替程控交换机中多频互控芯片而设计的,使用的DSP资源比较单一,还有很多功能由它来完成,取代原来部分芯片的功能,从而降低了成本,缩小产品体积。更多还原

【Abstract】 Basing on MFC theory, a new idea about realizing 30/32 channels MFC in DSP5402 chip is suggested. The details of implementation is described in this paper. This scheme is designed to supplant MFC chip in program control switch, it use DSP’s source is simple. There many function are completed by DSP chip to replace former chip’s function, so it can reduce the cose and the product’s bulk.更多还原
