随着电子技术和计算机技术的发展，电子产品已与计算机紧密相连，电子产品的智能化日益完善，电路的集成度越来越高，而产品的更新周期却越来越短。电子设计自动化（EDA）技术，使得电子线路的设计人员能在计算机上完成电路的功能设计、逻辑设计、性能分析、时序测试直至印刷电路板的自动设计。EDA是在计算机辅助设计（CAD）技术的基础上发展起来的计算机设计软件系统。与早期的CAD软件相比，EDA软件的自动化程度更高、功能更完善、运行速度更快，而且操作界面友善，有良好的数据开放性和互换性。 电子工作平台Electronics Workbench (EWB)(现称为MultiSim) 软件是加拿大Interactive Image Technologies公司于八十年代末、九十年代初推出的电子电路仿真的虚拟电子工作台,本文是对其做的一个使用说明。

RFID is an area of automatic identifi cation that is gaining momentum and is considered by some to emerge as one of the most pervasive computing technologies in history. In its simplest form, RFID is a similar concept to bar coding. It is seen as a means of enhancing data processes and is comple- mentary to existing technologies. It is a proven technology that has been in use since the 1970s.

This paper shows the development of a 1024-point radix-4 FFT VHDL core for applications in hardware signal processing, targeting low-cost FPGA technologies. The developed core is targeted into a Xilinx庐 Spartan鈩?3 XC3S200 FPGA with the inclusion of a VGA display interface and an external 16-bit data acquisition system for performance evaluation purposes. Several tests were performed in order to verify FFT core functionality, besides the time performance analysis highlights the core advantages over commercially available DSPs and Pentium-based PCs. The core is compared with similar third party IP cores targeting resourceful FPGA technologies. The novelty of this work is to provide a lowcost, resource efficient core for spectrum analysis applications.
