RZ/V2H AI SDK Configuration
This page explains the details of RZ/V2H AI SDK configurations.
To see the overview of RZ/V2H AI SDK, see RZ/V AI SDK Overview page.
Target Version: 5.00
Linux Components
The Linux components which are commonly used in RZ/V2H AI SDK is shown below.| Component | Version | Explanation |
|---|---|---|
| Yocto Linux |
Yocto version: 3.1.31 (Dunfell)
Kernel version: 5.10.145-cip17 |
|
| OpenCV | 4.1.0 | |
| OpenCL | 1.1, 1.2, 2.0 Full Profile. | |
| 3.0 Full Profile |
This is not guaranteed to be backwards compatible with the previous versions of OpenCL. |
|
| OpenGLES | 1.1, 2.0, 3.0, 3.1 and 3.2 | |
| OpenMAX IL | 1.1 |
This is used for H.264 encoding/decoding and H.265 encoding/decoding. |

Limitations
RZ/V2H AI SDK v5.00 has the following limitations.- RZ/V2H Linux BSP supports CPU/CA55 operation at 1.1 GHz, 1.5 GHz, 1.6 GHz, and 1.7 GHz. It does not support CPU/CA55 operation at 1.8 GHz.
- When using the ISP equipped camera e-CAM22_CURZH, supported transfer size is only combinations with HD (1280x720), 30 fps, 2 cameras (Total access bytes = 1843200 x 30 x 2) or less.
- 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.
