摘要： Mechanisms are provided for evicting cache lines from an instruction cache of the data processing system. The mechanisms store, for a portion of code in a current cache line, a linked list of call sites that directly or indirectly target the portion of code in the current cache line. A determination is made as to whether the current cache line is to be evicted from the instruction cache. The linked list of call sites is processed to identify one or more rewritten branch instructions having associated branch stubs, that either directly or indirectly target the portion of code in the current cache line. In addition, the one or more rewritten branch instructions are rewritten to restore the one or more rewritten branch instructions to an original state based on information in the associated branch stubs.

摘要： Reducing coherency problems in a data processing system is provided. Source code that is to be compiled is received and analyzed to identify at least one of a plurality of loops that contain a memory reference. A determination is made as to whether the memory reference is an access to a global memory that should be handled by a direct buffer. Responsive to an indication that the memory reference is an access to the global memory that should be handled by the direct buffer, the memory reference is marked for direct buffer transformation. The direct buffer transformation is then applied to the memory reference.

摘要： A method identifies the presence of a three-dimensional (3D) image format in received image through the use of feature matching and correspondence. The received image is sampled using a candidate 3D format to generate two sub-images from the received image. Initially, these sub-images are compared to determine whether these sub-images are similar with respect to structure. If the sub-images are not similar, a new 3D format is selected and the method is repeated. If the sub-images are similar, features are detected in the two sub-images and a correspondence is formed between features that match in the two sub-images. Positional differences are computed between corresponding features. The amount and uniformity of the positional differences are then used to determine whether the format is 2D or 3D and, if 3D, which of the 3D formats was used for the received image.

摘要： Prefetching irregular memory references into a software controlled cache is provided. A compiler analyzes source code to identify at least one of a plurality of loops that contain an irregular memory reference. The compiler determines if the irregular memory reference within the at least one loop is a candidate for optimization. Responsive to an indication that the irregular memory reference may be optimized, the compiler determines if the irregular memory reference is valid for prefetching. Responsive to an indication that the irregular memory reference is valid for prefetching, a store statement for an address of the irregular memory reference is inserted into the at least one loop. A runtime library call is inserted into a prefetch runtime library for the irregular memory reference. Data associated with the irregular memory reference is prefetched into the software controlled cache when the runtime library call is invoked.
