摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译： 存储在SRAM单元中的数据例如在长时间的空闲周期之前被周期性翻转。 以“翻转”模式和“非翻转”模式操作存储器有助于使偏置温度不稳定（BTI）劣化成对称，从而不会降低单元的静态噪声余量（SNM）降级。 存储在存储单元中的数据通过读出数据，反转读出数据以及将反相读出数据写入到存储器位置来翻转，直到SRAM的存储器位置被读出和写入。 当存储器以翻转模式操作时，从存储器读取和写入存储器的数据被反转以保持对存储器用户的透明度。 在经过一段时间的翻转模式下操作数据之后，将存储在存储器中的翻转数据重新提供以非翻转模式操作。

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.

摘要： 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.
