基于FPGA的多接口PCM传输系统的设计
Multi-Interface PCM Transmission System Design Based on FPGA
摘要
Abstract
In telemetry systems,in order to solve the problems that single-interface test system is not universal, and the application conditions are limited comparatively ,a multi-interface data transmission system using FPGA as control core was designed. The system transmits frame synchronization signals and the shift pulse signals through the RS422 interface meanwhile receiving PCM code ,communicates with the host computer by serial inter⁃face USB and parallel interface PCI ,and then read PCM data and analysis. PCI interface using a single access combined with burst access data transfer mode,USB interface adopts the FT245 with integrated agreement. The long-term tests prove that the system work stably and transmitted reliably with good genarality ,which meets the re⁃quirements of design.关键词
