Ten years ago, in grad school, I co-wrote a video conferencing module in VHDL [0]. I haven't touched HDLs since but here's what I remember very clearly from that project: * It took > 3 minutes to compile our code. * DMA made a huge performance difference once we figured it out. * Realizing that we had to be one with the clock tick took a lot of time. Understanding synchronous based programming (if that's the term) was a paradigm shift for my partner and I. * The utter delight when we got frames streaming across the wire. The performance (though over a LAN) was silky smooth and you could tell immediately this was different than the run-of-the-mill x86 desktop program.
