A system and method are provided for sensing a physical stimulus of an integrated circuit. The system and method operate with one or more active thermal sensors embedded in the die of an integrated circuit to provide highly accurate die temperature measurements. The system and method are able to monitor and control the die temperature of the integrated circuit to avoid an integrated circuit malfunction due to an undesirable temperature condition.
摘要:
A sensor and method are provided for sensing a physical stimulus in an integrated amount, such as thermal energy and produce a signal that indicates a quantitative value of the physical stimulus along with a value that indicates the operability of the sensor and a value that indicates a sense operation is in process. The sensor and method minimize the number of input and output pins necessary for a sensor to report a measurement response of a physical stimulus.

A method is provided in which a first error test may be performed on a memory that includes an integrated error correcting code (ECC) portion. The functionality of the ECC portion may be bypassed in the first error test. A second error test may be performed on the memory, where the second error test includes testing the functionality of the ECC portion. Also provided is an apparatus including a memory device and an error correcting code (ECC) circuit. The apparatus also includes a first switching device adapted to select a first input signal or a second input signal and a second switching device adapted to select one of a signal from the memory device or a signal from a portion of the ECC circuit. Also provided are computer readable storage devices encoded with data for adapting a manufacturing facility to create the apparatus and for adapting a processor to perform the method above.

Processor overclocking techniques are disclosed. Upon automatically determining that overclocking entry criteria are satisfied, one or more cores are clocked above their standard operation frequencies. The cores may be overclocked until one or more exit criteria are satisfied. At that point, an exit procedure is performed, with the one or more overclocked cores return to their normal operating frequency.

A method for producing a plurality of clock signals. The method includes generating a reference clock signal using a phase locked loop (PLL). The reference clock signal is then provided to each of a plurality of clock divider units which each divide the received reference clock signal to produce a corresponding divided clock signal. The method then removes one or more clock cycles (per a given number of cycles) in order to produce a plurality of domain clock signals each having an effective frequency based on a frequency and a number of cycles removed from the correspondingly received divided clock signal.

Data stored in SRAM cells are periodically flipped e.g., before long idle periods. Operating the memories in both a ‘flipped’ mode and a ‘non-flipped’ mode helps cause the Bias Temperature Instability (BTI) degradation to be symmetric, thereby not degrading the Static Noise Margin (SNM) degradation of the cells. The data stored in memory locations is flipped by reading out the data, inverting the read out data, and writing the inverted read out data into the memory locations until the memory locations of the SRAM have been read out and written. When the memory operates in flipped mode, data read from and written into the memory is inverted to maintain transparency to the memory user. After operating the data in flipped mode for a period of time, the flipped data stored in the memory is reflipped to operate in the non-flipped mode.

The present invention provides methods and memory structures for efficient tracking and recycling of physical register assignments. The disclosed methods and memory structures each provide an approach to reduce the size of the memory structures needed to track the usage of the physical registers and the recycling of these registers.
摘要:
A system and method for memory structures for efficient tracking and recycling of physical register assignments are disclosed. The method and system provide the necessary functionality to allow the number of physical registers assigned to incoming instructions to equal the number of physical registers that are returned to the list of free registers each cycle, thereby maintaining a substantially constant number of physical register pointers in the list of free registers. The system and method reduce the size of the memory structures utilized to track the usage of physical registers and the recycling of these registers.

The present invention provides a memory array having an array structure that has at least one memory cell, including a word write bit line and a single transfer line. The memory array is also provided with a two-stage memory cell having a speculative storage node, a non-speculative storage node, and a circuit. The two-stage memory cell is electrically coupled to the array structure. Activation of the circuit causes a speculative data value stored in the speculative storage node to be written to the non-speculative storage node.
