摘要
PCI是DSP应用系统与通用计算机高速通信的理想接口。介绍了一种双谱段探测系统的PCI接口方案,该方案采用TI公司的TMS320F2812 DSP作为控制单元主控芯片,采用Cypress公司PCI-DP系列的CY7C09449PV作为PCI接口芯片,具有接口简单方便易于实现的优点。详细讨论了CY7C09449PV与TMS320F2812的硬件连接、参数配置与时序分析。
PCI is an ideal interface for high-speed communication between DSP application system and general computer. A scheme of Dual-spectrum detection system with PCI interface has been developed, in which the CYTC09449PV of Cypress PCI-DP family is used as PCI interface chip, and TMS320F2812 of TI Company is used as main-control chip for the control unit of the system. The hardware connection between CY7C09449PV and TMS320F2812, parameter configuration and timing analysis is discussed.
