EX USB FX3 with large amount of video data

yakac_3966841 · ‎Jan 03, 2019

I need to transfer to PC video data with 120 FPS, 10 bit per pixel, 800x480 resolution. I was wondering if the EZ USB FX3 can do this. As far as I understand, if I need 10 bit per pixel this is effectively 16, so two pixels take all the 32 bits oft the GPIO and there is no room for LV and FV signals. Am I right? IS there an efficient way to configure the device given the above video parameters?

Hello,

Please see the attached images. When using 16-bit interface (Capture0.png), the data lines are GPIO[0:15] whereas when using 32-bit interface (Capture1.png), the data lines are GPIO[0:15], GPIO[33:44], GPIO[46:49]. Please hover on the GPIO number displayed to see the complete list of GPIOs used as the data lines.

Also, when using 32 bit interface, make sure that the LD_DATA_COUNT, LD_ADDR_COUNT in the GPIF II waveform are changed to 4191 (as per the documentation of AN75779).

Best regards,
Srinath S
