    • Display hardware which manages a plurality, e.g. three, potentially overlapping display windows each having its own pixel values and potentially having its own palette, with no limitation as to the position of the windows relative to each other. This capability is provided at a reduced hardware complexity as compared to a parallel hardware approach, by arranging substantial portions of the hardware in a multiplexed fashion so that the same hardware handles the lookup of palette entries for pixel values, regardless of the currently active window. The hardware is arranged so that it may switch in real time from processing data for one window to processing data for another window, whenever the current display coordinate crosses a window boundary.
    • 显示硬件,其管理多个,例如 三个可能重叠的显示窗口各自具有其自己的像素值并且潜在地具有其自己的调色板,对于窗口相对于彼此的位置没有限制。 与并行硬件方法相比,通过以多路复用的方式布置硬件的大部分,使得相同的硬件处理像素值的调色板条目的查找,而不管当前活动的窗口如何,提供了这种能力。 硬件被布置为使得当当前显示坐标跨越窗口边界​​时,它可以实时地从一个窗口的处理数据切换到另一个窗口的处理数据。

    • An apparatus and method for efficient memory utilization in an electronic system comprises a memory divided into memory units of equal size, a data source, and an interface between the memory and the data source, which manages storage and retrieval of data in the memory. The data source generates first data components and second data components, each of the first data components being larger than each of the second data components. Each memory unit is sized to contain one of the second data components. The memory units are configured as a continuous memory ring. The interface stores the data components sequentially in the memory ring as the data components are generated by the data source. The interface also retrieves the data components sequentially from the memory ring. A control module sends control signals to the interface to control read and write operations for the data components.
    • 一种用于电子系统中有效的存储器利用的装置和方法包括:分配成相等大小的存储单元的存储器,数据源以及存储器和数据源之间的接口,其管理存储器中的数据的存储和检索。 数据源产生第一数据分量和第二数据分量,每个第一数据分量大于每个第二数据分量。 每个存储器单元的尺寸被设置为包含第二数据组件之一。存储器单元被配置为连续存储器环。 由于数据源由数据分量生成,接口将数据组件顺序存储在存储环中。 该接口还从存储环中顺序检索数据组件。 控制模块向接口发送控制信号,以控制数据组件的读写操作。
