摘要
以Cirrus Logic公司的ARM芯片和TI公司的TMS320V DSP为例,研究了ARM与DSP的数据接口———HPI接口的相关技术,并给出了在HPI接口非复用模式下,CS89712与C5510的信号连接图和嵌入式实时操作系统uCOS-II下驱动程序的部分关键源代码。
Taking CS89712 from Cirrus Logic corporation and TMS320VC5510 from TI corporation for example, The technology of data interface between ARM and DSP using HPI interface is studied. Moreover, CS89712 and C5510's signal connections in the HPI's nonmultiplexed mode and the driver based on uCOS- Ⅱ are given out.
