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 ).
