    • An image display apparatus that detects a picture defect and shifts an image region to eliminate the picture defect. The image display apparatus includes a memory unit that temporarily stores an input image signal, a memory control unit that controls a readout start address for the memory unit, a display unit to which the image signal read out of the memory unit is supplied, a detection unit that detects an aspect ratio of the input image signal, and an address control signal generation unit which receives an output from detection unit and generates a readout start address control signal for the memory unit.

    • A cache-memory control apparatus controls a level-1 (L1) cache and a level-2 (L2) cache having a cache line divided into a plurality of sub-lines for storing data from the L1 cache. The cache-memory control apparatus includes a control-flag adding unit, an L1 cache control unit, and an L2 cache control unit. The control-flag adding unit provides an SP flag to each of the sub-lines. The L1-cache control unit acquires an access virtual address, and, when there is no data at the access virtual address, outputs an L2 cache-access address to the L2-cache control unit. The L2-cache control unit switches the SP flag based on a virtual page number in an L1 index and a physical page number in an L2 index. Based on the SP flag, corresponding one of the sub-lines is written back to the L1 cache.
    • 高速缓冲存储器控制装置控制一级(L1)高速缓存和二级(L2)高速缓存,该缓存具有被划分成用于存储来自L1高速缓存的数据的多条子行的高速缓存行。 高速缓冲存储器控制装置包括控制标志添加单元,L1高速缓存控制单元和L2高速缓存控制单元。 控制标志添加单元向每个子线提供SP标志。 L1高速缓存控制单元获取访问虚拟地址,并且当在访问虚拟地址处没有数据时,向L2高速缓存控制单元输出L2高速缓存访​​问地址。 L2缓存控制单元基于L1索引中的虚拟页号和L2索引中的物理页号来切换SP标志。 基于SP标志,相应的一条子行被写回到L1高速缓存。

    • The present invention provides a television receiver which receives television signals to display images on a CRT display, and includes a JPEG decode unit (21) for decoding JPEG (Joint Photographic Experts Group) compressed image data. The JPEG decode unit (21) detects image size of image data after decode processing stored in JPEG compressed image data from a memory card (6). In case the image size is larger than image display area of a CRT display (3) and activity ratio of a memory unit (22) is larger than a limit value, the JPEG decode unit (21) sends the image size to a CPU (25), and concurrently decodes the JPEG compressed image data in the memory unit (22) to generate the image data, and clips away half of the image data along the vertical direction and the horizontal direction. The image data process unit (23) enlarges or reduces the image data so that the image data is displayed on substantially the whole image display area without changing the aspect ratio of the image data based on enlargement/reduction ratio which is determined by the CPU (25) by comparing the image size with the image display area of the CRT display (3).
    • 本发明提供一种电视接收机,其接收电视信号以在CRT显示器上显示图像,并且包括用于解码JPEG(联合图像专家组)压缩图像数据的JPEG解码单元(21)。 JPEG解码单元(21)从存储卡(6)检测存储在JPEG压缩图像数据中的解码处理之后的图像数据的图像尺寸。 在图像尺寸大于CRT显示器(3)的图像显示区域并且存储器单元(22)的活动比大于限制值的情况下,JPEG解码单元(21)将图像大小发送到CPU( 25),并且同时解码存储单元(22)中的JPEG压缩图像数据以生成图像数据,并且沿着垂直方向和水平方向剪切掉图像数据的一半。 图像数据处理单元(23)放大或缩小图像数据,使得图像数据基本上显示在整个图像显示区域上,而不改变由CPU确定的放大/缩小比例的图像数据的宽高比( 25),通过将图像尺寸与CRT显示器(3)的图像显示区域进行比较。
