Comparing to traditional device exploitation,the PCI device exploitation based on TMS320C6416 decreases the difficulty in hardware and software design because of the inline PCI interface.This paper discussed PCI bus Linux Driver exploitation based on C6000 DSPs,posed a data transfer method based on DMA,submit the key source code.%TI公司的TMS320C6000系列DSP由于有了内置PCI接口,因此大大提高了数据传输速度,同时提高了数据传输的可靠性以及系统的稳定性。本文以工程项目为背景,详细讨论了以TMS320C6416DSP为核心的PCI总线的Linux驱动程序开发方法,根据DSP PCI总线的特点,提出了基于DMA方式的数据传输机制,给出了关键源码。
