关于C6678通过QMSS产生中断



1.PDSP产生的中断(PUSH到704队列),除了产生中断外是否还进行像PKTDMA一样进行搬数。

2.我想核0给核1发送数据(PKTDMA)后,当数据传完后给核1一个中断请问怎么设计?

  • 704为高优先级累加器队列,当你把他设置为接收队列,是可以产生中断的,并且数据也发送了过来,队列里压入的就是用于接收的描述符。核0给核1发数据产生中断,也可以直接采用高优先级累加器中断,具体看多核导航中断映射章节5.2

  • 1)搬数需要用infra structure queue 

    QMSS TX queues. Used for infrastructure (core to core) DMA copies and notification

    2)用TX QUEUE数据发完后,用queue pend queue传递中断event
