The RZ/V Series has two version of the Image Signal Processor (ISP)
RZ/V2L Simple ISP Support Package
RZV/2M Full ISP Support Package
RZ/V2L Simple ISP (Memory)
The Simple ISP uses a working memory area for processing camera streams. This working memory area is defined in the device memory space define ISP Reserved memory area ( see Figure ). In the Application Layer uses the Video 4 Linux API (VIDIOC_REQBUFS, VIDIOC_QUERYBUF) to allocated memory. How much of this memory is used is defined by the camera device resolution, pixel color depth, and capture frame buffer count. The ISP revered memory space is defined in the RZV2L Linux Device Tree File ( r9a07g04512-smarc.dts ).
RZV2L BSP v1.0.1 Memory Area
| OV5645 Supported Resolutions | ||||
| Width | Height | Pixel Depth | Number Frames | Total Memory Usage |
| 640 | 480 | 2 | 6 | 3,686,400 |
| 1280 | 720 | 2 | 6 | 11,059,200 |

1 The number of frames is reduced to fit inside the ISP Reserved Memory Area for BSP v1.0.1 ( 48MB ).
RZ/V2L ISP Monitor Demo
RZ/V2L ISP Sample Camera Demo
This demo show how to implement the RZ/V2L Simple ISP with OV5645 Cameras. This expands on the RZ/V2L ISP Sample Application that is included with the RZ/V2L ISP Package with all the resolutions listed in the section above.
