TDA4VM: PCIE and DSP issue

EVAN
Prodigy 140 points
Part Number: TDA4VM

Hi ；

Please help me confirm some problems about TDA4VM。

1：Can the C7x DSP or C66x DSP be used for audio processing?

2：When TDA4VM as PCIE EP，two PCIE3.0 x2 interface  connect CPU (PCIE3.0 x4)  ，Has the bandwidth doubled relative to PCIe3.0 x2？ Is the internal DMA space sufficient ?

Thanks；

Best wishes

    1. Yes. However, we don't have audio example in SDK.

    2. PCIe 3.0 x4 has 2x BW comparing PCIe 3.0 x2 at the physical link layer. However, with system/SW overhead, you may not get exactly 2x performance at the application level.

    I am not sure what you meant by DMA space. DMA can handle the traffic/throughput from PCIe if that's what you were asking.
