total camera data rate: 2x (stereo camera) 720x1280 (resolution) x10 (bit depth) x120 (framerate)

2*720*1280*10*120/(1024^3) = 2.05993652Gbps

this is lower than the usb 3 bandwidth, and we can do 90fps if we ever need 4 cameras

need to verify: axi4 bandwidth, algorithm pipeline bandwidth, HSPI bandwidth/freq
