Note
If the system does not work properly, such as the stream stopping,
when using DRP-AI TVM in combination with a camera connected via MIPI, USB or Ethernet, please apply the bus setting patch.
This patch sets the number of bytes per access to minimize the impact on operations between units when each RZ/V2H unit accesses the DDR.
Please apply this patch with caution after thorough verification.

For how to apply the patch, please refer the How to Build RZ/V2H AI SDK.

Limitations
RZ/V2H AI SDK v5.20 has the following limitations.- Some AI models with frequent memory accesses may affect the performance of other LSI functions that access memory. We are considering to improve this issue in the next release version.
