TDA4VM: VPAC和DMPAC和C6X/C7X使用问题

Baiqing Wang
Part Number: TDA4VM


从TDA4VM 手册中，有这样的内容：The VPAC works as front end to vision processing and prepares frame/scales for further processing by other vision accelerators or processor cores in the SoC. 如果说VPAC和DMPAC只能R5核访问的话，那么是不是camera输入后的视觉处理及控制都要R5核来做？那么ADAS功能的camera image perception没办法在A72核做了？也就是ADAS的视觉相关处理都在R5核来做了？如何更A72核衔接呢？A72核和R5核如何分工合作？谢谢！
