The idea is that it&rsquo;s an abstraction atop what a CPU is really doing, allowing you to see what a given flow of ASM code is doing in a visual representation of its effect, rather than worrying about nitty details of things like paging tables and stack frames and so forth that don&rsquo;t matter to 99% of coders.<\/p><\/blockquote>","protected":false},"excerpt":{"rendered":"<p>Gwynne Raskind: This tool is intended to present an active visual representation of the execution of a virtual CPU.
