摘要： A reference signal input of a delay locked loop is connected to receive a reference clock. The delay locked loop provides a drive clock that drives a clock distribution tree. One of the endpoints of the clock distribution tree is connected to a feedback reference of the delay locked loop. By using one the endpoints as a feedback loop to the delay locked loop the signal received at components attached to the endpoints of the distribution tree can be synchronized to the reference input received at the delay locked loop.

摘要： Apparatus and methods for storing data in a block to provide improved accessibility of the stored data in two or more dimensions. The data is loaded into memory macros constituting a row of the block such that sequential values in the data are loaded into sequential memory macros. The data loaded in the row is circularly shifted a predetermined number of columns relative to the preceding row. The circularly shifted row of data is stored, and the process is repeated until a predetermined number of rows of data are stored. A two dimensional (2D) data block is thereby formed. Each memory macro is a predetermined number of bits wide and each column is one memory macro wide.

摘要： 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. 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.

摘要： A memory interface allows access to SDRAM by receiving a column address for a data read or write of a burst of data units. Each data unit in the burst has an expected bit size. The interface generates n (n>1) column memory addresses from the received column address. The interface accesses the synchronous dynamic memory to read or write n bursts of data at the n column memory addresses. Preferably, the SDRAM is clocked at n times the rate of the interconnected memory accessing device, and the memory units. The data units in the n bursts preferably have one nth the expected bit size. In this way, SDRAM may be accessed with high memory bandwidth, without requiring an increase in the size of data units in the SDRAM, and the associated data bus. Conveniently, the interface may be operable in two separate modes or configurations. In one mode, SDRAM may be accessed through the interface in a conventional manner. In the second mode, SDRAM is accessed in multiple bursts for each received burst access. The interface may form part of a memory accessing device, or may be a separate component for use with such a device.
