【摘要】 微机保护经历多年发展后 ,系统各方面的性能都有了跨越式的发展。随着微电子技术的进步 ,出现了DSP以及CPLD/FPGA等高集成度、超大规模的芯片。本文将探讨CPLD/FPGA与DSP的各种组成方式构成的保护设计方案 ,包括DSP的外围芯片式专用信号处理芯片式及片上系统 (SOC)式 ,并提出多DSP控制式的设计方案。分析了各种方式的典型配置 ,给出详细的比较及应用场合。更多还原

【Abstract】 After microprocessor-based protection has dev el oped through many years,the performance has made a great progress. With the deve lopment of the electronic technique,the chip in high density appeared such as DS P and CPLD/FPGA. This paper will try to discuss all kinds of modes made up by D SP and CPLD/FPGA,in which CPLD/FPGA act as peripheral fetch chip,special digital processor and system-on-chip mode. This paper will also propose a novel mode which CPLD controlls DSPs.更多还原
