     *Discussions about various implementations of LFSRs, Reed-Solomon/Viterbi/etc... codecs, accumulators for DSP, etc...

     *Most online info about Hardware Description Languages (HDLs) is pretty poor. I've collected here the best references I've found, generally aimed at Verilog. The coding style guides are not about mere aesthetics or convention, but show how to write correctly synthesizable code. It'll save you a lot of headaches.

     *Most instructions online about this topic are aimed at Ubuntu Linux, which is subtly different enough from Debian Stable for them to not work. I've worked them out here for plain Debian.

     *Excellent and thorough work-through on how to properly infer various kinds of memories from HDL code. Quotes the relevant documentation.
