AMD patents hybrid x86 technology: low-power cores set to return

AMD has been granted a patent for heterogeneous microprocessors featuring two types of general-purpose cores. The technology resembles Arm’s famous Big.Little architecture and could be used for CPUs aimed at mobile and low-power devices. 

The patent outlines a microprocessor featuring two types of general-purpose cores running two different subsets of the same instruction set architecture (ISA). The first type of cores is set to support a larger subset of the ISA and feature high performance, whereas the second type of simplified cores is configured to consume less power. Different types of cores can share memory locations as well as cache.
