Team Status Report<\/strong><\/p>\n

UPDATES<\/u><\/p>\n

This week, we had a presentation! We’ve posted the slides<\/a>\u00a0from that, as well the poster<\/a>\u00a0for our demo, under media.<\/p>\n

RISKS<\/span><\/p>\n

We have a viable demo currently. We have some improvements that we’d like to make in terms of processing speed, but our current demo constitutes our minimum viable project.<\/p>\n

DESIGN CHANGES<\/span><\/p>\n

The DMA solution from last week was successful, so we have incorporated that into our project. The DMA engine transfers pixel data to the BRAM, then transfers the resulting energies back to the DRAM when the computation is complete.<\/p>\n

Personal work and Progress:<\/em><\/p>\n

I spent most of this week debugging the DMA solution.\u00a0Now that the system works, we can officially say that DMA is correct and faster than the alternative. For a 3.7 second video, the energy computation time decreased from 144s to 11s. These are the newest timing data I’ve collected:<\/p>\n
