摘要

介绍了Samsung公司的32位ARM9核的S3C2440微处理器和Philips公司的CAN控制器SJA1000的特点，并按时序要求，采用了基于CPLD可编程逻辑芯片，实现了CPU与CAN控制器之间接口的实现电路，以及在Linux下驱动的实现方法。提供了非多路复用总线与分时多路复用总线的转换连接的基本思路。

Abstract

This paper described the characteristics of Samsung Corporation 32-bit ARM9 microprocessor core S3C2440 and Philips’s CAN controller SJA1000. According to time sequence requirements, the interface circuit between CPU and CAN controller had been realized by using programmable logic chips based on CPLD. The drive method had also been achieved under Linux. This paper provided the basic idea of connection conversion between non-multiplexed bus and time-multiplexed bus.
