片上系统 ( SOC)的设计是以模块复用和软硬件协同设计为基础 ,基于平台的设计则以新产品开发中尽量减少模块的重新设计并尽量少增加新的模块为出发点。文中提出了基于 SOC的可配置微机保护硬件平台的设计方法和具体实现 ,该平台由 FPGA和微处理器以及相关接口构成。由于 FPGA有可重复编程的特点 ,不仅芯片中的保护算法、通信模块等可以重新配置 ,构成 SOC骨架结构的模块也可以重新配置。微处理器是 Flash结构 ,也支持在线修改 ,因此该平台的应用非常灵活 ,极大地缩短了新产品的开发周期。文中给出平台应用的 3种典型配置方案 ,其应用领域涉及从基本的电流三段式保护到基于小波变换的变压器暂态保护等方法
System-on-chip (SOC) design is based on modular reuse and hardware / software co-design, while platform-based design starts with new product development that minimizes the redesign of modules and minimizes the addition of new modules. In this paper, a design method and implementation of configurable microcomputer protection hardware platform based on SOC are proposed. The platform consists of FPGA and microprocessor and related interfaces. Due to the reprogrammable nature of FPGAs, not only the protection algorithms and communication modules in the chip can be reconfigured, but the modules that make up the SOC architecture can also be reconfigured. Microprocessor Flash architecture, also supports online modifications, so the application of the platform is very flexible, greatly shortening the development cycle of new products. The paper presents three typical configuration options for platform applications. The application areas range from basic current three-stage protection to transformer transient protection based on wavelet transform
