Been there, done that! https://en.wikipedia.org/wiki/Jazelle https://en.wikipedia.org/wiki/Jazelle Jazelle was an instruction set extension to allow natively running java bytecode on Arm processors. Arm never seemed to give it any proper care and attention necessary for it to make any actual market impact, they didn't even publish the ABI. Transmeta, that used to employ Linus Torvalds at one stage, had Code Morphing Software: https://en.wikipedia.org/wiki/Transmeta#Code_Morphing_Software https://en.wikipedia.org/wiki/Transmeta#Code_Morphing_Softwa... It was built in to the silicon, that essentially operated as a full JIT for x86 software, translating to back-end VLIW instruction set. Transmeta seemed heavy on the marketing and buzz (hiring Linus was very much a marketing move), light on the actual execution. Crusoe didn't even remotely live up to their own buzz and it just about killed off their chances of success.
