    • 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.

    • The present invention is directed to an improved memory and I/O bridge that provides an improved interface for communicating data between the data bus of the system processor and the memory controller. The memory and I/O bus bridge according to the present invention provides increased performance in the system. The memory and I/O bridge can include a deep memory access request FIFO to queue up memory access requests when the memory controller is busy. The memory and I/O bridge can include a memory write data buffer for holding and merging memory write operations to the same page of memory. The memory and I/O bridge can include a memory read data buffer for holding and queuing data and instructions read from memory, waiting to be forward to the data bus. The memory data read buffer can operate in one or more software selectable prefetch modes, which can cause one or more pages to be read in response to a single memory read instruction. The memory read data buffer can satisfy memory read request for data or instructions already held in the memory read buffer without reading the data or instructions from memory. The memory read data buffer can also provide for data coherency with respect the memory write data buffer and the external memory. The memory and I/O bridge can also include performance counters for tracking information about the performance of the memory and I/O bridge in order to tune the software operation and determine the optimum prefetch mode for a given application.

    • A screwdriver comprises a torque setting mechanism including a torque adjustment ring, an actuation rod threadedly secured to the upper torque adjustment ring and a lower torque adjustment nut, a spring biased sleeve with the actuation rod passed, and a clutch ring snugly put on two opposing intermediate flats of the actuation rod and having an upper surface engaged the torque adjustment ring and a lower surface formed with recesses engaged with steel balls on an upper surface of a support ring in the sleeve. Turning a rotatable handle will turn the sleeve. The clutch ring will disengage with the steel balls if the torque exceeds a set value. Thus, the torque exerted on the handle will not transmit to a shank secured to the actuation rod so as to prevent a screw from being over-driven by the shank.
