Configure Large Volume FPGA in Communication Measurement System
Abstract:This article introduces a system implementation method of configuring FPGA through PCI interface of DSP chips. The method is developed on a basis of thorough research on FPGA configuration solutions and requirement of measurement system for wireless networks. Here, basic flow of the implementation method and key problems in configuration process are presented. In this way, FPGA can be configured neatly and completely software-based. The design described in this article has passed the hardware test, and has been applied in the system of terminal testing successfully.
