From the project
MIPI DSI transmitter core for Xilinx FPGAs (work in progress)
This is a work-in-progress core to interface advanced MIPI DSI displays with a Xilinx 7-series FPGA. The current display target is the Sony Z5 Premium LCD (AUO H546UAN01.0 or Sharp LS055D1SX05) which is a 5.5" 4k (2160x3840) LCD. At the moment I am running it in a mode where content is upscaled by the panel from 1080x1920, as 4k content must be compressed using VESA DSC or Qualcomm FBC. I am working on an encoder for the former.
