    摘要： According to one embodiment, a state manager classifies an area allocated to the multi-core processor in a first memory area into one of a first state in which allocation to processor cores is not performed, a second state in which allocation to one of the processor cores is performed and read and write are performed, and a third state in which allocation to one or more of the processor cores is performed and read and write are prohibited, and further performs a transition from one of the first state, the second state, and the third state to another. A cache/memory manager writes back a corresponding cache when the state manager performs the transition from the second state to the third state.

    摘要： A four-cycle internal combustion engine with a valve system having improved durability in the case of high revolution speed. The engine includes a cylinder head having a port, and a valve having a stem part continuous with a fillet part for opening or closing the port. A valve spring including inner and outer springs urges the valve in a direction to close the port. A valve guide holds the stem part slidably. A tubular spring guide supports an outer periphery part of an outer spring to prevent lateral deformation of the spring. A top end of the spring guide is positioned above a top end of a valve guide.

    摘要： A method and apparatus for selectively scaling portions of image data based on the intensity levels of historical image data. The selective scaling, or level expansion, provides improved images by increasing or decreasing the intensity of a portion of image pixels. Black level expansion reduces the intensity of dark pixels and is appropriate when a relatively large number of the image pixels have a high intensity level. White level expansion increases the intensity of bright pixels and is appropriate when a relatively large number of image pixels have a low intensity level. Level expansion is implemented by using histogram comparators 402 to compare the intensity of each pixel with a threshold, typically on a frame-by-frame basis. When an adequate number of pixels in each frame meet the threshold criteria, the level expansion is increased. Field accumulator 404 is used to determine whether and by how much the image data is scaled. Field accumulator 404 increments each time a frame meets the expansion criteria, as determined by the histogram comparators 402, and decrements each time a frame does not meet the expansion criteria. The value accumulated by the field accumulator 404 is used by level expander 406 to scale at least a portion of the input data.

    摘要翻译： 一种用于基于历史图像数据的强度级别选择性地缩放图像数据的部分的方法和装置。 选择性缩放或电平扩展通过增加或减少图像像素的一部分的强度来提供改进的图像。 黑色电平扩展会降低暗像素的强度，并且在相对较大数量的图像像素具有高亮度水平时是合适的。 白平衡扩展增加亮像素的强度，并且当相对大量的图像像素具有低强度水平时是合适的。 通过使用直方图比较器402，通常在逐帧的基础上比较每个像素的强度与阈值来实现电平扩展。 当每帧中足够数量的像素满足阈值标准时，级别扩展就会增加。 场累加器404用于确定是否和通过多少图像数据被缩放。 场累加器404每当帧满足由直方图比较器402所确定的扩展标准时增量，并且每当帧不符合扩展标准时递减。 由场累加器404累积的值由电平扩展器406用于缩放输入数据的至少一部分。
