One of my research areas is security or trust enhancements in compilation. Synthesis, too. Almost all of that work focuses on 32-64 bits due to limitations of lower ones. Yet, I keep seeing projects such as this and SymbOS that blow my mind in what can be done with so little hardware. I think the implementation techniques used in them probably contain plenty of wisdom that could lead to improvements in embedded compiler and metaprogramming research. Maybe even 32-64 bit systems in just making better usage of resources.<p>Need to have a whole collection of articles for implementing HLL constructs and algorithms effectively in 8-16 bit systems. Maybe 4bit while we&#x27;re at it to give these 8-bit show-offs a challenge. ;)<p>EDIT: Editing to add the interesting link below I found on 4-bit computing courtesy of Wikipedia&#x27;s article on 4-bit. Interesting part was how manufacturers brought offer to developers as invite only. Wonder if they&#x27;ve since transitioned to 8-bit.<p><a href="http:&#x2F;&#x2F;www.embeddedinsights.com&#x2F;channels&#x2F;2010&#x2F;12&#x2F;10&#x2F;considerations-for-4-bit-processing&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.embeddedinsights.com&#x2F;channels&#x2F;2010&#x2F;12&#x2F;10&#x2F;consider...</a>
