基于FPGA的控制器局部网(CAN)总线控制器设计

A Design of Controller Area Network(CAN) Bus Controller Based on FPGA

提出一种基于FPGA的CAN总线控制器的实现方案,给出其结构框图,并对内部各模块进行较为详细的介绍。最后给出控制器在A ltera公司的系列FPGA上实现时的资源利用情况及其性能,并参照CAN协议规范对其进行仿真验证。

A method for implementing controller area network（CAN） bus controller is presented in this paper. With the block diagram of the controller,each module is explained in detail. The controller is implemented based on ALTERA FPGAS and the resource utilization and performance is listed then. Finally,a test program is produced to-check whether the CAN protocol is correctly implemented in the model of the implementation.
