This is haste, because I am off on holiday tomorrow. One is customisable instruction sets, where an application can load a restricted set of instruction patterns, which map into a lower level hardware ISA. Very like the Pentium 4, but customisable. Push that up a level and it becomes very much an interpretation method. You lose some advantages of compilation, but gain others (e.g. compactness). Regards, Nick Maclaren.
