It almost reads like a US Patent document of some kind. Trying to verify that, I came across something even more interesting: http://appft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-adv.html&r=7&f=G&l=50&d=PG01&S1=zIIP.BIS.&OS=spec/zIIP&RS=SPEC/zIIP United States Patent Application 20080059769 MULTIPLE-CORE PROCESSOR SUPPORTING MULTIPLE INSTRUCTION SET ARCHITECTURES A multiple-core processor supporting multiple instruction set architectures provides a power-efficient and flexible platform for virtual machine environments requiring multiple support for multiple instruction set architectures (ISAs). The processor includes multiple cores having disparate native ISAs and that may be selectively enabled for operation, so that power is conserved when support for a particular ISA is not required of the processor. The multiple cores may share a common first level cache and be mutually-exclusively selected for operation, or multiple level-one caches may be provided, one associated with each of the cores and the cores operated as needed, including simultaneous execution of disparate ISAs. A hypervisor controls operation of the cores and locates a core and enables it if necessary when a request to instantiate a virtual machine having a specified ISA is received. And a little further down, in the Description section: The present invention relates generally to data processing systems, and more particularly, to processors for running multiple virtual machines having disparate instruction set architectures.
