摘要: Techniques are disclosed for parallel computing of a line of sight (LoS) map (e.g., view-shed) in a parallel computing system. For example, a method for computing an LoS map comprises the following steps. Data representing at least one image is obtained. An observation point in the at least one image is identified. A portion of the data that is associated with a given area in the image is partitioned into a plurality of sub-areas. The plurality of sub-areas are assigned to a plurality of processor elements of a parallel computing system, respectively, such that the data associated with each one of the plurality of sub-areas is processed independent from the data associated with each other of the plurality of sub-areas, wherein results of the processing by the processor elements represents the LoS map. The parallel computing system may be a multicore processor.

摘要: A computer readable medium is provided embodying instructions executable by a processor to perform a method for caching video data in a two-dimensional cache. The method includes storing the video data in the two-dimensional cache, addressing stored video data in the two-dimensional cache using a first tag for referencing video data of a first dimension, addressing the stored video data in the cache in terms of a second tag for referencing video data of a second dimension, and retrieving and outputting a portion of the stored video data from the two-dimensional cache according to one of the first tag and the second tag.
