摘要： A computer graphics system includes a plurality of geometry accelerators for processing vertex data representative of graphics primitives and providing rendering data. The system includes a distributor responsive to a stream of vertex data for distributing to the geometry accelerators chunks of the vertex data for processing by the geometry accelerators to provide chunks of rendering data. The distributor generates an end of chunk bit indicative of the end of each of the chunks of vertex data. The system further includes a concentrator for receiving the chunks of rendering data from each of the geometry accelerators and for combining the chunks of rendering data into a stream of rendering data in response to end of chunk bits. The stream of rendering data and the stream of vertex data represent sequences of graphics primitives having the same order. A rasterizer generates pixel data representative of a graphics display in response to the stream of rendering data.

摘要： A translation look-aside buffer (TLB) is described. The TLB may include a memory populated with pointers to collections (e.g., tables) of virtual-to-physical address translations. The memory may be populated by, for example, a page fault logic in response to resolving a page fault. The TLB may also include a signal logic to receive a virtual address and to selectively provide either a miss signal or a pointer to a collection of virtual-to-physical translations. The signal may provide the miss signal upon determining that the virtual address is not associated with a stored pointer and may provide a pointer upon determining that the virtual address is associated with the pointer.

摘要： Apparatus for receiving and automatically storing data words according to magnitude is provided. A self-sorting stack embodying the invention comprises a sorting device comprising means for simultaneously comparing the incoming data with the contents of each stack register, and logic and switching means for automatically inserting the new data into the correct register on the stack while at the same time pushing the contents of that and subsequent registers down one location. The entire operation is performed in one clock cycle, the same as for a conventional nonsorting stack.

摘要： A memory control system is provided with a directory cache and a memory controller. The directory cache has a plurality of directory cache entries configured to store information regarding copies of memory lines stored in a plurality of memory caches, wherein each directory cache entry has one or more bits configured to store an ownership state that indicates whether a corresponding master directory entry lacks a memory cache owner. The memory controller is configured to free for re-use ones of the directory cache entries by 1) accessing a particular directory entry, and 2) determining whether the ownership state of the particular directory cache entry indicates that a corresponding master directory entry lacks a memory cache owner. If so, the memory controller A) skips a master directory update process, and B) claims for re-use the particular directory cache entry.

摘要： A directory cache is provided with a plurality of directory entries configured to store information regarding copies of memory lines stored in a plurality of caches. The entries are divided into sets of N entries, with each set of N entries being addressable via an index. The directory cache is also provided with a cache controller. The cache controller retrieves a set of N entries associated with an index corresponding to a memory line, and if a tag portion of one of the retrieved entries corresponds to the memory line, the cache controller determines whether the one of the retrieved entries contains an indication that information regarding the memory line is stored in at least a second one of the retrieved entries.

摘要： Coherency directory updating is provided in a multiprocessor computing system. A plurality of memory resources have a directory, and are operably connected to an interconnect fabric. A cell is operably connected to the interconnect fabric. The cell has a cache including an entry for each of a plurality of coherency units, each coherency unit included in a memory block representing a contiguous portion of the plurality of memory resources. A controller is operably connected to the interconnect fabric. The controller is configured to control a portion of the plurality of memory resources, and has a comparator configured to identify whether a memory block is local. If the memory block is local, the controller is configured to set a state of the directory to exclusive for a write transaction. If the memory block is not local, the controller is configured to set the state to invalid for a write transaction.
