    • Encoding a video signal according to a scalable video coding (SVC) technique employs two different encoding paths for the base layer and the enhancement layers respectively, whereby the two encoding paths share common hardware encoding modules. For example, a control module can route received video information associated with the base layer directly to the hardware encoder modules for encoding, while routing video information associated with the enhancement layers to an upscaler. The upscaled video information is then provided to the hardware encoder module for processing in similar fashion to the base layer information. The hardware encoder provides encoded video information to another control module, which determines whether to route the information to a hardware or software entropy encoder, based on whether the encoded video information is associated with the base layer or an enhancement layer, respectively.
    • 根据可伸缩视频编码(SVC)技术编码视频信号分别为基本层和增强层使用两种不同的编码路径,由此两个编码路径共享共同的硬件编码模块。 例如,当将与增强层相关联的视频信息路由到升档器时,控制模块可以将接收到的与基本层相关联的视频信息直接路由到硬件编码器模块进行编码。 然后将放大的视频信息提供给硬件编码器模块,以与基本层信息类似的方式进行处理。 硬件编码器将编码视频信息提供给另一个控制模块,该控制模块基于编码视频信息是分别与基本层还是增强层相关联来确定是否将信息路由到硬件或软件熵编码器。

    • A low power charge pump is disclosed. A pump driving node of a first pump stage is selectively coupled to a pump driving node of the subsequent pump stage. Subsequent to a transfer of charge from a first pump stage to a subsequent stage, the first and subsequent pump driving nodes are coupled. Residual charge on a first stage pump driving node is thereby transferred to a subsequent pump driving node. Subsequent to the transfer of charge from the first pump driving node to the second pump driving node, the nodes are uncoupled. By selectively coupling a first pump stage to a pump driving node of the subsequent pump stage, the first pump driving node may pre-charge the subsequent pump driving node, thereby reducing the energy that must be provided by clock driving circuitry to produce a positive-going transition of a driving clock. Advantageously, pre-charging energy is taken from the first stage, reducing the energy that was heretofore dissipated by clock driving circuitry during a negative-going clock signal transition. In this novel manner conversion efficiency of a charge pump device may be beneficially increased, providing enhanced low power performance.
    • 公开了一种低功率电荷泵。 第一泵级的泵驱动节点选择性地联接到后续泵级的泵驱动节点。 在将电荷从第一泵阶段转移到后续阶段之后,第一和随后的泵驱动节点被联接。 因此,第一级泵驱动节点上的剩余电荷被转移到随后的泵驱动节点。 在将电荷从第一泵驱动节点转移到第二泵驱动节点之后,节点分离。 通过选择性地将第一泵级耦合到后续泵级的泵驱动节点,第一泵驱动节点可以预先对后续的泵驱动节点进行预充电,从而减少必须由时钟驱动电路提供的能量, 驾驶时钟的过渡。 有利地,从第一级获取预充电能量,减少在负向时钟信号转换期间由时钟驱动电路消耗的能量。 以这种新颖的方式,可以有利地增加电荷泵装置的转换效率,从而提供增强的低功率性能。

    • A method and system for reading flash memory. A leakage current of a common bit line comprising the flash memory cell is accessed. A read current of the flash memory cell is accessed. The leakage current is eliminated from the read current to determine a cell current. The cell current is compared to an erase verify cell current. The currents may be directly subtracted, or they may be converted to corresponding voltages and the voltages subtracted. Advantageously, cells may be correctly verified for erasure without a preliminary search and recovery of over erased bits. As a beneficial result, the search and recovery of over erased bits does not need to be performed during an erase process. Advantageously, such steps may be eliminated from an erase process, recovering the time otherwise required to perform such steps, and thereby speeding up the erase process.
