TI中文支持网Part Number:PROCESSOR-SDK-AM62A
Dear TI Processor Community,
Now we need to porting a dtof sensor to the AM62A platform. I have the following questions that I need help clarifying:
1.The maximum frame rate processed by ISP on Linux platform，we only need to capture raw data;;
2. The formats width height and frame rates of the sensor in various working modes are as follows:
pcm :
image (raw12) data size: 32 (width) 55296 (height), maximum 2fps (frame rate)
echo:
image (raw12) data size: 480 (width) 4096 (height), maximum 20fps (frame rate)
ranging:
image (raw12) data size: 228 (width) 4096 (height), maximum 25fps (frame rate)
histogram:
image (raw12) data size: 2688 (width) 6144 (height), maximum 6fps (frame rate)
Is it supported? If it is not supported, please indicate the maximum value supported, thank you.

请看下面的FAQ。https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1303374/faq-am62a7-what-s-the-maximum-camera-resolution-and-frame-rate-supported-by-am62a

Dear TI Processor Community, Thank you very much for the prompt reply. Our maximum rate on the CSI-2 Rx interface is only 3Gbps, which is less than 5Gbps, and the platform meets the requirements. At the same time, our maximum pixel rate is less than 200MPixel/second, less than 315MPixel/second, and the platform also meets the requirements, but please help confirm. one time: 1. Is there a minimum limit on line width? 2.Is there a maximum and minimum limit on height? 3. Does the width and height need to be an integer multiple of a certain value?

请看下面TRM文档, 最大支持8MP分辨率，最大line width是4096– Performance: Up to 1 pixel per clock cycle processing and 8MP resolution (4096 line width) support (see OPP table for clock speed per derivative, assumes 100% utilization so assume typical 20% de-rate for headroom). (per approved CR: PROC_SOC-4948) https://www.ti.com/lit/ug/spruj16b/spruj16b.pdf

Dear Shine:
意思和linux操作系统相关的具体实现，你这边不能提供更多信息？有些芯片厂商在具体的软件实现时，会对最小width有要求，也可能要求width和height需要是某个值（例如32）的整数倍。

Shine：
我和产品线工程师确认一下哈。

Shine：
下面是工程师的回复。Regarding the ISP, the only limit is that the line width must be smaller than 4096.
