Interfacing external FIFO with STM32F767ZI to shift ip camera data into FPGA

Dear all,

I have an IP Camera which i have interfaced with STM32F767ZI. I m able to command the camera over ethernet (RTSP) and recieve RTP packets containing video data over UDP. Further i wish to interface STM32F767ZI with 2 FIFOs . These FIFOs will be used to store video data (ie. payload of RTP packets). The FIFOs will be read by FPGA and further processing on data will be done on FPGA.(Two FIFOs are required so that while 1 FIFO is being written by MCU , the other is to read by FPGA . Hence there will be no loss of packets).

My probelm is I wish to write FIFO at high frequency so that no UDP ethernet packets are lost. For this i want 32 bit data to be pushed to FIFO with highest possible frequency clock. Can you please help me write a code in C to synchronously shift 32bit data into my external FIFO.

Hello @ggaut​, it is very good for you. If you can share the details of your project. People can make use of your information.

information grows when it shared.
