摘要： A method is provided for associating an address with data. The method includes precharging a matchline connected to a plurality of tag match functions to a first potential, wherein each tag match function comprises one or more match logic devices, discharging two tag lines for a first tag bit to ground, and reading a plurality of tag bits and corresponding data bits onto a plurality of tag lines and a plurality of data lines respectively. The method further includes determining a match between the tag bits and data bits, and pulling the matchline to a second potential upon determining a match for each of the tag bits.

摘要： A method is provided for selecting a participant to issue. The method includes signaling a domino OR gate arbitration device upon a ready request of a participant having a priority, determining within the domino OR gate arbitration device the relative priority of the participant, signaling the domino OR gate arbitration device through an any-request device upon the ready request of a higher priority participant, and issuing the higher priority participant upon determining the higher priority participant to have a priority highest among participants ready for issue. The method includes gating one of a precharge signal and an evaluate signal of the precharged domino OR gate arbitration device by the ready request of the participant. The method further includes latching a result of the domino OR gate arbitration device and a clock signal, and gating the clock signal by the ready signal of the participant.

摘要： Leakage current control devices include a circuit having one or more functions in a data path where the functions are executed in a sequence. Each of the functions has power reduction logic to energize each respective function. A leakage control circuit interacts with the power reduction logic, so that the functions are energized or deenergized in a control sequence such that the functions where the data is resident are energized and at least one of the other functions is not energized.

摘要： An integrated circuit including a pipeline and a method of operating the pipeline. Each stage of the pipeline is triggered by one or more triggering events and are individually, and selectively, stalled by a stall signal. For each stage a stall signal, delayed with respect to the stall signal of a downstream stage, is generated and used to select whether the pipeline stage in question is triggered. A data valid signal propagating with valid data adds further selection, such that only stages with valid data are stalled.

摘要： A synchronous integrated circuit such as a scalar processor or superscalar processor. Circuit components or units are clocked by and synchronized to a common system clock. At least two of the clocked units include multiple register stages, e.g., pipeline stages. A local clock generator in each clocked unit combines the common system clock and stall status from one or more other units to adjust register clock frequency up or down.

摘要： Mechanisms are provided for predicting effects of soft errors on an integrated circuit device design. A data processing system is configured to implement a unified derating tool that includes a machine derating front-end engine used to generate machine derating information, and an application derating front-end engine used to generate application derating information, for the integrated circuit device design. The machine derating front-end engine executes a simulation of the integrated circuit device design to generate the machine derating information. The application derating front-end engine executes an application workload on existing hardware similar in architecture to the integrated circuit device design and injects a fault into the existing hardware during execution of the application workload to generate application derating information. The machine derating information is combined with the application derating information to generate at least one soft error rate value for the integrated circuit device design.
