System Design : MIPI Rx interface to PCIe

hi, I want to design a system which need to transfer the video data from a camera to a processor,as my processor motherboard doesnt have a MIPI interface i want to tranfer the same through Fpga whe...

Hi Sir, 1. No, this can’t directly interface the Avalon ST between MIPI RX and PCie ST since the data format or standard is difference. You have to decode and translate it if you wanna use the PCIe to transmit the date. Please refer to the PCIe IP avalon ST user guide for more detail info. 2. If this is Avalon MM slave interface, then you can use any Avalon MM master port to access it. For example, Nios II processor, or you can create a state machine to read it out. Please refer to the Avalon specification for more detail. https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/manual/mnl_avalon_spec.pdf 3. The following example design of PCIe may be helpful to you https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an829.pdf https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an456.pdf Regards -SK

hi SK Lim,

thanks for the reply.

if I need to interface the Avalon ST of MIPI CSI2 to a buffer for eg: on chip memory and the read part of the buffer is an Avalon MM interface of PCIe endpoint then how to find the size of the buffer?

if you have some reference can you please share it.

thanks and regards
