For the eighth week of work on the project, I didn’t work on the project that much due to Carnival. I ran into a wall regarding the bandwidth issues from last week. We received the wifi antennas that we were hoping would fix the issues, but in initial tests, we were still strangely getting the same bandwidth as before. I tried to bring the Pis home to test it on a different network, and I ended up with the same results. Thus, without really knowing what to do, I decided to turn my attention to the array transmission portion of the project. I pivoted away from the H264 streams that we used in the interim demo, and I updated my code for sending arrays of pixel values across a socket. Based on the packet loss we were experiencing in the demo, I’ve thought about using TCP as the transmission protocol, but for now, I’ve implemented both TCP and UDP, and we’ll see how it goes. Essentially, where we are right now is that with time running out, we might just have to settle for the bandwidth issues and focus on integration so that we have a completed product by the final deadlines. I plan to continue troubleshooting the bandwidth issues this week along with fully testing my array transmission.

Personal accomplishments this week:
- Continued working on compute pipeline and implemented most of non-max suppression using HLS Windows. Had a bug that resulted in more suppressed pixels than what is expected.
- Looked into HLS streams and VDMA for higher performance since using regular DMA adds more work.
- Made some progress on memory interfacing, but still need to implement unit test and software side of interface.
- Carnival – less work than expected during 2nd half of the week.
Progress on schedule:
- Since I’ve been working with Edric, I’m still behind where I would like to be on the memory interface. I’m planning on going back to the memory interface on Monday, but I’ll likely still support Edric as necessary. I will be out on Wednesday to have a follow-up with a doctor, so I anticipate having the memory interface done on the 17th.
Deliverables next week:
Memory interface prototype using unit test to verify functionality (if possible), bug-free implementation of NMS.
