ISP Bandwidth on Xavier AGX

Hi,

We have a customer using Xavier AGX and multiple cameras passing through the ISP for debayering. They want to achieve higher frame rates but in order to determine if it is possible in theory, we would like to know what is the max bandwidth (BW) on the ISP. I read on the datasheet that for TX2, TX1 and others the ISP can process 1400MP/s, does Xavier AGX has the same BW? The customer seems to measure 1600MP/s.

Thanks,
-David

hello DavidSoto-RidgeRun,

FYI, it depend-on the clock rate on the platform, ISP can process 2 pixels/clock.
so, it’s possible if the ISP clock rate is ~800 MHz,
thanks

Hi JerryChang,

Thanks for the answer, what is the maximum CLK supported by the ISP? That will help us to understand the maximum amount of pixels per second.

hello DavidSoto-RidgeRun,

you may grant root permission and check the maximum clock rate from system node,
for example,

# cat /sys/kernel/debug/bpmp/debug/clk/isp/max_rate
1190400000
