摘要
针对CAN总线要实现高速数据交换的要求,要实现PC机与CAN总线之间的数据传送,双端口RAM就要在PC机和适配卡之间建立双向的数据交换通道。本文主要介绍双端口RAM的特点、功能及硬件判优工作方式在CAN总线适配卡中的应用。
Realize the demand for high-speed data interchange to CAN bus will realize the data transmission between the PC and CAN bus, pairs of port soon in PC and right to mix card set up the two-way data interchange pass way RAM. This text introduce pairs of characteristic, function, hardware, port of RAM arbitrate working way in bus right to buy application of the card CAN mainly.
