摘要： To encode and compress a data array 30, the data array 30 is first divided into a plurality of blocks 31. A quadtree representation is then generated for each block 31 by initializing each leaf node of the quadtree to the value of the data element of the block 31 of the data array 30 that the leaf node corresponds to, and initializing each non-leaf node to the minimum value of its child nodes, and then subtracting from each node except the root node the value of its parent node. A set of data indicating the differences between respective parent and child node values in the quadtree representing the block of the data array is then generated and stored, together with a set of data representing a quadtree indicating the number of bits that have been used to signal the respective difference values.

摘要： The present invention provides a data processing apparatus and method of controlling access to a shared resource. The data processing apparatus has a plurality of processors operable to perform respective data processing operations requiring access to the shared resource, and a path is provided interconnecting the plurality of processors. An access control mechanism is operable to control access to the shared resource by the plurality of processors, each processor being operable to enter a power saving mode if access to the shared resource is required but the access control mechanism is preventing access to the shared resource by that processor. Further, each processor is operable, when that processor has access to the shared resource, to issue a notification on the path when access to the shared resource is no longer required by that processor. A processor in the power saving mode is arranged, upon receipt of that notification, to exit the power saving mode and to seek access to the shared resource. This approach has been found to result in significant power savings.
