    摘要: A data processing system includes a central processing unit (CPU) in communication with a system memory. Within the system memory, there is stored legacy code that does not utilize the full features of the CPU. The data processing system also includes a code-optimizing coprocessor in communication with the CPU and the system memory. Control logic within the code-optimizing coprocessor causes the code-optimizing coprocessor to generate optimized code from the legacy code at the same time the CPU executes the legacy code, such that the optimized code is tailored according to the CPU. After the code-optimizing coprocessor has generated at least some optimized code, the code-optimizing coprocessor causes the CPU to automatically utilize at least some optimized code in lieu of at least some of the legacy code.

    摘要: A method and system for storing and modifying register transfer language (RTL) described logic types. Upon a declaration of a signal interconnect, a language extension of a register transfer language is defined for the signal interconnect based on the signal interconnect's type. The language extensions allow different signal interconnect types, such as those used with field programmable gate arrays (FPGA) and standard cells, to be stored in a same file array hierarchy. This storage facilitates changing logic types, thus ultimately resulting in an integrated circuit (IC) that is either smaller (using more standard cells) or more flexible (using more FPGA cells). The transition from one RTL type to another is performed within the physical design cycle, in which wiring, timing and placement of components (information) is performed before masking out the final chip design.

    摘要: In a first aspect, a method is provided for conserving power in a processing integrated circuit. The method includes the steps of (1) calculating power consumption for executing an instruction and data corresponding to the instruction; and (2) executing the instruction if such execution does not exceed a predetermined power level. In a second aspect, a method is provided for conserving power in a processing integrated circuit employing a plurality of execution units. The method includes the steps of (1) comparing a total power to be consumed by the processing integrated circuit to a power budget for the processing integrated circuit; and (2) if the total power exceeds the power budget, freezing execution of an instruction by one of the plurality of execution units so as to allow execution of the instruction to continue at a later time from where execution was frozen. Numerous other aspects are provided, as are systems and apparatus.

    摘要: A system and method for providing on-chip voltage distribution and regulation. In accordance with the system of the present invention, an IC chip includes a source voltage plane having a source supply rail for supplying power to the IC chip and a source ground rail for sinking power supplied therefrom. At least one intermediate ground rail is connected between the source supply rail and the source ground rail to divide the source voltage plane into multiple intermediate voltage planes. The intermediate ground rail serves as a supply rail for a subsequent intermediate voltage plane such that the intermediate voltage planes are series-connected.
