  • Method for processing a macro block of image data
    Patent number: 7920757
    Abstract: The image data are coded with field DCT or frame DCT depending on the characteristics of the image data. However different coding types will result in different boundary marks of boundaries between adjacent blocks or adjacent macro blocks. Therefore the de-blocking of a boundary between two adjacent blocks or adjacent macro blocks should be performed according to the format of image data and the coding type of the adjacent blocks or adjacent macro blocks.

  • Error correction apparatus and method for data stored in memory
    Patent number: 7917826
    Abstract: An error correction device includes a main memory, a memory bus coupled to the main memory, and a correction module. The correction module is coupled to the system bus and directly connected to the memory bus. The correction module reads an error data from the main memory via the memory bus according to an error address, generates a correct data according to the error data and an error value, and directly writes the correct data into the main memory via the memory bus. Because the correction module reads and writes the correct data into the main memory without using the system bus managed by an arbitrator, a number of the change row operations can be reduced to increase system efficiency.

  • Error correction apparatus and method thereof
    Patent number: 7823045
    Abstract: An error correction device includes a decoding unit, an error buffer, an error classifying unit and an error correction unit. The decoding unit reads data from a main memory and performs error detection on the data to generate error values and error addresses. Then, the error buffer temporarily stores the error values and the error addresses. The error classifying unit classifies the error addresses stored in the error buffer into a plurality of subclasses, where error values and error addresses which correspond to the same row of the main memory are classified into the same subclass. Finally, the error correction unit performs an error correction on the data stored in the main memory according to the plurality of subclasses. The error correction device therefore can reduce the amount of the change-row operations of the main memory so that the memory efficiency is increased.

    Abstract: A method of measuring a numerical aperture of an exposure machine is described. A control wafer having vernier marks thereon and an aberration mask having pinholes therein are provided, wherein each pinhole corresponds to a vernier mark in position. A lithography process using the exposure machine and the aberration mask is performed to the control wafer, so as to form over each vernier mark a photoresist pattern having the same shape of the illumination pattern of the light source of the exposure machine. The numerical aperture of the exposure machine is then derived from a graduation of the vernier mark corresponding to an outer edge of the photoresist pattern.
