Abstract
A decompression unit is configured to partially decompress a compressed image formed by compressed tiles. Each compressed tiles correspond to a tile of the uncompressed image. The decompression unit selects a subset of relevant tiles, which are visible in a view window or a view frustum. Specifically, the decompression unit includes a tile selector to select the relevant tile and a tile decompressor to decompress the relevant tiles. By decompressing only a subset of the compressed tiles, the decompression unit reduces the processing time required to generate the contents of the view window.
