Report for My Summer Work on the Mic Array Project

I wrote a report for my summer work on the microphone array as a required submission for my summer lab intern. The report is written in the format of a short conference paper and presents my part of the work on the microphone array project in detail, so I think it is worth being put on this website. To summarize, more rigorous tests on the CIC and the FIR filter’s performance were conducted using both simulation and the real hardware after the FIR filter was working. I started working on the Ethernet data transmission in mid August but the combined system is still not working. We can now send and receive constant data using the Triple-Speed Ethernet IP Core given by Intel, but the data interfaces of the filter and the Ethernet IP core are quite different so we need to figure out the glue logic between the two interfaces.
