大家好 问一下 在STK_C6657包 SRIO例程中
SRIO_Packet_Type packet_type[]=
{
SRIO_PKT_TYPE_SWRITE ,
//SRIO_PKT_TYPE_NWRITE ,
//SRIO_PKT_TYPE_NWRITE_R ,
SRIO_PKT_TYPE_NREAD ,
SRIO_PKT_TYPE9_STREAM ,
SRIO_PKT_TYPE11_MESSAGE
};
SRIO_PKT_TYPE_SWRITE 这是流写操作
SRIO_PKT_TYPE9_STREAM 这个也是流写操作么???是Data Streaming???这个不是直接IO/DMA 也不是消息传递吧?
和SRIO_PKT_TYPE_SWRITE 有什么区别
建议您先参阅SRIO specification:http://www.rapidio.org/files/encapspec.pdf
看来TYPE9数据包格式是指数据流和扩展数据流类。
