基于FPGA的PLC浮点运算系统的设计与实现
Design and implementation of PLC floating-point operation system based on FPGA
摘要
Abstract
Aiming at slowness and low accuracy problem of traditional PLC floating-point controller,a PLC floating-point operation system based on FPGA is proposed.According to compilation principle,the program conversion software IEC_ TO_FPGA is designed.The standard IEC 61131-3 structured text language is converted Verilog HDL language.By studying the IEEE754 standard floating-point representations addition and subtraction,multiplication and division rules,the hardware description language Verilog HDL is used to achieve a single-precision floating-point basic addition and subtraction,multiplication and division.In the Quartus II environment,the generated program is simulated,which verifies the feasibility of the FPGA-PLC floating point computing system.关键词
