摘要： A design structure for an integrated circuit (IC) including a decoder decoding instructions, shadow latches storing instructions as a localized loop, and a state machine controlling the decoder and the plurality of shadow latches. When the state machine identifies instructions that are the same as those stored in the localized loop, it deactivates the decoder and activates the plurality of shadow latches to retrieve and execute the localized loop in place of the instructions provided by the decoder. Additionally, a method of providing localized control caching operations in an IC to reduce power dissipation is provided. The method includes initializing a state machine to control the IC, providing a plurality of shadow latches, decoding a set of instructions, detecting a loop of decoded instructions, caching the loop of decoded instructions in the shadow latches as a localized loop, detecting a loop end signal for the loop and stopping the caching of the localized loop.

摘要： A method and system for supporting simultaneous operation of operating systems on a single integrated circuit. The system includes a supervisory operating system (SOS) managing execution of instructions, each instruction being executable under one of the operating systems; registers grouped into multiple sets of registers, each set maintaining an identity of one of the operating systems; and a dispatcher capable of dispatching an instruction and a tag attached to the instruction, the tag identifying one of the operating systems and the instruction to be executed under the identified operating system to access one of the registers. One or more of the registers are utilized when the instruction is executed, and are included in a single set of the multiple sets of registers. The single set maintains the identity of the operating system identified by the tag, and each of the one or more registers includes an identifier matching the tag.
