    摘要： A system and method of providing error detection and correction capability in an IC using redundant logic cells and an embedded field programmable gate array (FPGA). The system and method provide error correction (EC) to enable a defective logic function implemented within an IC chip design to be replaced, wherein at least one embedded FPGA is provided in the IC chip to perform a logic function. If a defective logic function is identified in the IC design, the embedded FPGA is programmed to correctly perform the defective logic function. All inputs in an input cone of logic of the defective logic function are identified and are directed into the embedded FPGA, such that the embedded FPGA performs the logic function of the defective logic function. All outputs in an output cone of logic of the defective logic function are identified, and the output of the FPGA is directed to the output cone of logic of the defective logic function, such that logic EC is provided within the embedded FPGA structure of the IC chip.

    摘要： A method and system for reducing clock noises are disclosed. A clock signal includes active edges and inactive edges. Inactive edges produce clock noise but are not critical to the functionality of the clock signal. That is, only active edges are critical to proper timing of an integrated circuit (IC). As such, inactive edges of clock signals to clocked elements of an IC may be shifted to be misaligned to one another. As a consequence, peak noise produced by the inactive edges will be spread over a large area and therefore will be reduced in amplitude.

    摘要： 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： An integrated circuit device includes functional logic, an anti-noise machine, and state monitoring points providing the anti-noise machine with an interface to the functional logic for monitoring states of the functional logic. The anti-noise machine includes indicia defining noise precursor states for the functional logic, and recognition logic coupled to the state monitoring points. The anti-noise machine is operable to generate anti-noise responsive to the recognition logic detecting in the functional logic noise precursor states matching the indicia.
