1- Star_Extract_IP.v
The image processing “star extraction” via centroding module
2- The clocking management IP [AXI4 (Clock wizard v5.1 provided by Vivado 2015.2) Or (Clock wizard v5.3 provided by Vivado 2016.4)
The purpose is to multiply the input clock coming from the camera = 72MHz by 4 to obtain a faster clock being able to make the This IP provides many features including: a. Frequency Synthesizer This is the main unit doing the frequency generation of different frequencies.
b. Phase Alignment
1- The image processing part Part 1: [initialization] It is responsible for instantiating the clocking management unit. “The clocking wizard IP instance” Part 2: [runs at the shifted input clock from the camera] 72MHz shifted by 270] It is responsible for transferring pixels from the camera to the FPGA internal memory holding only the stream window of size = 7 rows. Part 3: [runs at the faster clock 288 MHz] The star extraction and image processing stuff is done here. 2- The clocking management part 3- The test bench “Simulation Purposes Only”
