Embodiment Construction

[0017] In an illustrative embodiment of the invention, image data within a computer system is transferred from slower memory to faster, cyclically configured memory for processing. Details of exemplary embodiments are discussed below.

[0018] figure 1 is a schematic diagram of an example computer system upon which illustrative embodiments can be implemented. figure 1 The example computer system 100 in is for illustrative purposes only and should not be considered as a limitation of the present invention. Although the following description refers to terms commonly used to describe a particular computer system, the concepts described are equally applicable to other computer systems, including figure 1 The structures shown are not similarly constructed systems.

[0019] The computer 100 includes a central processing unit (CPU) 105 having a conventional microprocessor, a main memory 110 (such as random access memory, commonly referred to in the art as "RAM") for temporarily st...

Abstract

A relatively high speed circular memory device, in combination with other processes, improves image processing efficiency. To that end, a method and apparatus of processing image data stored in an initial memory logically divides the image into a plurality of contiguous strips. A first plurality of the strips are stored in a working memory having a circular addressing arrangement, where the working memory is faster than the initial memory and has a plurality of sequential address locations. The first plurality of strips are contiguous and have a start address. In addition, the first plurality of strips are stored in the working memory in a contiguous manner, and processed through the working memory relative to the start address.

Description

technical field [0001] The present invention relates to memory management, and in particular, the present invention relates to improving memory efficiency within a graphics processing system. Background technique [0002] Among the many advantages of modern computer systems is their ability to produce realistic graphical displays. As a result, computer systems have become widely used tools in a variety of graphic fields, such as photography and graphic design. However, computer applications enhanced for this purpose have the effect of increasing the complexity of the design and, correspondingly, the complexity of the manufacturing image software. [0003] The prior art has responded to this need by adding more processing power to computer systems. For example, many computer systems have dedicated graphics processors that are specifically designed to reduce the computational load on the main processor. Consequently, many such computers have processing speeds that exceed th...
