本文采用Altera公司的FPGA器件Cyclone III系列EP3C10作為核心器件構(gòu)成了R-S（255，223）編碼系統(tǒng)；利用Quartus II 9.0作為硬件仿真平臺，用硬件描述語言Verilog_HDL實現(xiàn)編程，并且通過Jtag接口與EP3C10連接。R-S（Reed-Solomon）碼是一類糾錯能力很強的特殊的非二進制BCH碼，能應對隨機性和突發(fā)性錯誤，廣泛應用于各種通信系統(tǒng)中和保密系統(tǒng)中。R-S（255，223）碼能夠檢測32字節(jié)長度和糾錯16字節(jié)長度的連續(xù)數(shù)據(jù)錯誤信息。
This application note provides users with a general understanding of the SVF and XSVF fileformats as they apply to Xilinx devices. Some familiarity with IEEE STD 1149.1 (Jtag) isassumed. For information on using Serial Vector Format (SVF) and Xilinx Serial Vector Format(XSVF) files in embedded programming applications
This application note explains the XC9500™/XL/XV Boundary Scan interface anddemonstrates the software available for programming and testing XC9500/XL/XV CPLDs. Anappendix summarizes the iMPACT software operations and provides an overview of theadditional operations supported by XC9500/XL/XV CPLDs for in-system programming.
