Xiaojuan Shi

Abstract

Aiming at motion control card,a hardware implement scheme based on DSP+CPLD+ISA is proposed.Among the chip,DSP is TMS320LF2407A of TI Company and CPLD is EPM7256S of Altera Company.According the solutions,dual-port RAM communication circuit,I/O port address coding circuit,two axis control output and position detecting circuit based on CPLD of motion control card are designed and finished.The main control program and interrupt-serving program of DSP is designed in software.
