XAPP098 - Spartan FPGA低成本、高效率串行配置

This application note shows how to achieve low-cost, efficient serial configuration for Spartan FPGA designs. The approachrecommended here takes advantage of unused resources in a design, thereby reducing the cost, part count, memory size,and board space associated with the serial configuration circuitry. As a result, neither processor nor PROM needs to be fullydedicated to performing Spartan configuration.In particular, information is provided on how the idle processing time of an on-board controller can be used to loadconfiguration data from an off-board source. As a result, it is possible to upgrade a Spartan design in the field by sending thebitstream over a network.

扩频通信芯片STEL-2000A的FPGA实现

针对传统集成电路（ASIC）功能固定、升级困难等缺点，利用FPGA实现了扩频通信芯片STEL-2000A的核心功能。使用ISE提供的DDS IP核实现NCO模块，在下变频模块调用了硬核乘法器并引入CIC滤波器进行低通滤波，给出了DQPSK解调的原理和实现方法，推导出一种简便的引入?仔/4固定相移的实现方法。采用模块化的设计方法使用VHDL语言编写出源程序，在Virtex-II Pro 开发板上成功实现了整个系统。测试结果表明该系统正确实现了STEL-2000A的核心功能。 Abstract: To overcome drawbacks of ASIC such as fixed functionality and upgrade difficulty, FPGA was used to realize the core functions of STEL-2000A. This paper used the DDS IP core provided by ISE to realize the NCO module, called hard core multiplier and implemented CIC filter in the down converter, described the principle and implementation detail of the demodulation of DQPSK, and derived a simple method to introduce a fixed phase shift of ?仔/4. The VHDL source code was designed by modularity method , and the complete system was successfully implemented on Virtex-II Pro development board. Test results indicate that this system successfully realize the core function of the STEL-2000A.
