摘要
单片机具有传输速度快、可靠性高、使用灵活等优点,常常作为一种通信接口规范应用在PC外设和便携式系统中。利用单片机与大规模CPLD的互补性,介绍了基于EDA技术的单片机与FPGA/CPLD总线接口逻辑设计,并给出了该接口芯片的单片机控制程序的源程序。结果表明该总线接口逻辑电路工作稳定、可靠,已经在高速数据采集的PC外设上得到应用。
SCM (MCU) with high transmission speed, extremely reliability and flexibility, is widely used in pc peripherals and portable system as a communication interface standard. With complementary between SCM and large-scale CPLD, the article introduces the logic design based on FPGA/CPLD bus interface and gives the SCM source code for interface chip. the result indicates that the BUS interface logic circuit stable and reliable applies on the PC peripheral for high-speed data acquisition.
