My Task in this project is to combine 3 data stream source(Video, Sound, and UART) into 1 memory area, and then migrate it to SD card.
Video used ITU-R BT.601standard, compressed with JPEG algorithm, and send to Memory by using AXI DataMover IP Core.
The other source is I2S based audio from Audio Decoder and Uart Stream source.

This works is done using Vivado and Xilinx Zynq7000 FPGA
