Code Morphing Software (CMS) is the technology used by Transmeta microprocessors to execute x86 instructions. In broad view, CMS reads x86 instructions and generates instructions for a proprietary VLIW processor, in the style of Shade. CMS translation is much more expensive than Shade's, but produces much higher quality code. CMS also contains an interpreter and simulates both user-mode and system mode operation.
