| 摘 要： | 主要研究Windows CE.NET下ARM9与DSP间通过HPI通信的驱动程序开发，该驱动程序通过中断驱动模式控制数据的传输，以动态链接库的形式包含到Windows CE.NET操作系统中。ARM9通过此驱动程序可方便地读写DSP的片内、片外存储空间。在S3C2440A+TMS320C6713电路板上测得此驱动程序的数据传输速率可达100 Mbps，此研究对开发双CPU的数控系统有一定参考价值。

| Abstract: | This paper mainly studied the host-port interface (HPI) device driver for the communication between ARM9 and DSP microprocessor under Windows CE.NET, it worked on the interrupt-driven model and could be included into Windows CE.NET system in the form of dynamic link library. ARM9 could access the on-chip and off-chip memory storage filed of the DSP microprocessor through the HPI device driver quickly and the data transmission speed could reach 100 Mbps on the designed S3C2440A & TMS320C6713 printed circuit board. For the design of double CPUs numerical control system, there is certain external meaning of using for reference. |
