Abstract
A method and apparatus for loading data from memory to a cache is provided. The method and apparatus provide substantially improved performance, especially in conjunction with large data arrays for which each element of data is processed completely at once and need not be later accessed. A technique is provided to allow a data element to be loaded directly to a cache location corresponding to the local variable used to process that data element, thereby avoiding copying of the data element to multiple cache locations. In conjunction with the use of non-caching stores of processed results back into main memory, this technique completely avoids cache thrashing within the framework of a conventional microprocessor architecture. This technique is ideally suited for high-performance processing of streaming multimedia data including video processing.
