摘要
文章针对定点数字信号处理器(Digital Signal Processor,DSP)芯片TMS320LF2407的结构特点,介绍了该芯片最小系统电路的设计方法,包括时钟电路、复位电路、联合测试行动组(Joint Test Action Group,JTAG)仿真接口电路、外围存储器接口电路和电平转换电路,并结合实际应用情况,详细介绍了外扩控制器局域网(Controller Area Network,CAN)总线接口电路的设计。
This paper introduced the hardware design methods of the minimal system about TMS320LF2407, which was the fixed - point DSP chip, according to its structure （Introducing the relative circuits about Timing, Reset, JTAG Emulation and Memory Interfacing and Voltage Transition）. It also particularly introduced the design of expansion inter- facing circuit for CAN Bus, in terms of practical application.
