How much processing bandwidth can ISP support?(Jetson Nano)

How much bandwidth does Jetson Nano’s ISP support? Can it support 4Kp60?If not, can you recommend other collections

hello tiantianluxin,

according to Nano Product Design Guide, for your 4k@60-fps use-case, you may enable quad-lane camera, each data lane has a peak bandwidth of up to 1.5 Gbps.

you may also access L4T sources to check reference drivers.
for example,
below enable dual IMX219 running at 3264x2464@21-fps on Jetson-Nano.
$L4T_Sources/r32.4.2/Linux_for_Tegra/source/public/kernel_src/hardware/nvidia/platform/t210/porg/kernel-dts/porg-platforms/tegra210-camera-rbpcv2-dual-imx219.dtsi

suggest you may contact with Jetson preferred partners for supported cameras and also camera solutions.
thanks
