A method and system is provided for organizing and routing multiple memory requests from a plurality of clients to multiple memories. Requests from a plurality of clients, including a plurality of clients of the same type, such as multiple MPEG decoders, are directed to different memory controllers by a router. The memory controllers order the client requests by requests among similar client types. The memory controllers also order the client requests by different client types. The ordered requests are then delivered to memory. Returned data is sent back to the clients. A method of mapping motion pictures experts group (MPEG) video information for improved efficiency is presented, wherein image information is stored in blocks of memory referred to as tiles. Tiles are mapped in memory so that adjacent tiles only correspond to different banks of memory.

Memory controller for handling multiple clients and method thereof

A system and method for storing a multidimensional array of data, such as a two dimensional (2-D) array of video data, in a non-contiguous memory space. The system and method maps individually indexed elements of a multidimensional array of data from a source device into blocks of non-contiguous memory available in a destination memory system, even when the destination blocks are small and/or their size does not correlate in any way to the dimensions of a source buffer. In particular, the blocks of non-contiguous memory may be as small as a single element of the data indexed in the 2-D array.

System and method for transferring a multidimensional array of data to a non-contiguous buffer

System for testing multiple devices on a single system and method thereof

A memory controller for use in a computer system. The controller has a buffer having an input configured to receive read and write requests. Each request has an associated memory address. For a selected received request, prior received requests out of a set of the received requests are determined. For each determined prior received request, that request's memory address is compared to the selected request's memory address to see if they match. If a match exists, the selected request is prevented from being memory executed.
