摘要： A virtual address translation table and an on-chip address cache are usable for translating virtual addresses to physical addresses. Address translation information is provided using a cluster that is associated with some range of virtual addresses and that can be used to translate any virtual address in its range to a physical address, where the sizes of the ranges mapped by different clusters may be different. Clusters are stored in an address translation table that is indexed by virtual address so that, starting from any valid virtual address, the appropriate cluster for translating that address can be retrieved from the translation table. Recently retrieved clusters are stored in an on-chip cache, and a cached cluster can be used to translate any virtual address in its range without accessing the address translation table again.

摘要： Devices and methods provide data from multiple storage locations to a processor. A data block containing data required by a processor is stored in two or more locations, e.g., in a local memory and a system memory, both of which are accessible to the processor's memory interface. The memory interface directs each read request for mirrored data to one or another of the mirror locations. Selection of a mirror location to be read is based on substantially real-time information about which mirror location is best able to handle the request. For instance, the selection of a mirror location to access can be based at least in part on information about the level of activity on various buses that connect the processor to the mirror locations.

摘要： A cache shared by multiple clients implements a client specific policy for replacing entries in the event of a cache miss. A request from any client can hit any entry in the cache. For purposes of replacing entries, at least of the clients is restricted, and when a cache miss results from a request by the restricted client, the entry to be replaced is selected from a fixed subset of the cache entries. When a cache misses results from a request by any client other than the restricted client, any cache entry, including a restricted entry, can be selected to be replaced.

摘要： In a virtual memory system, address translation information is provided using a cluster that is associated with some range of virtual addresses and that can be used to translate any virtual address in its range to a physical address, where the sizes of the ranges mapped by different clusters may be different. Clusters are stored in an address translation table that is indexed by virtual address so that, starting from any valid virtual address, the appropriate cluster for translating that address can be retrieved from the translation table. The clusters are dynamically created from a fragmented pool of physical addresses as new virtual address mappings are requested by consumers of the virtual memory space.

摘要： Optimization logic that optimizes a stream of requests being transmitted onto a link by a link interface unit can be enabled or disabled based on a performance metric that represents a measure of the degree to which a response to a request is likely to be slowed due to congestion, propagation delays, or other bottlenecks in the system. For example, the performance metric can be based on a measured level of link activity due to requests from the transmitting device and/or a prediction as to behavior (e.g., access time) of the target device that receives the stream of requests. The control logic advantageously does not require extra signals to be carried on the bus.

摘要： A raster operations (ROP) unit interleaves read and write requests for efficiently communicating with a frame buffer via a PCI Express (PCI E) link or other system bus that provides separate upstream and downstream data transfer paths. One example of a ROP unit processes pixels in groups, performing read modify writeback sequences for each group. The read requests associated with pixels in a second group are advantageously interleaved with the writeback requests for pixels in the first group prior to sending the requests on the system bus.
摘要翻译： 光栅操作（ROP）单元经由PCI Express（PCI E）链路或提供单独的上游和下游数据传输路径的其他系统总线交错读写请求以有效地与帧缓冲器通信。 ROP单元的一个示例处理组中的像素，对每个组执行读修改回写序列。 与第二组中的像素相关联的读取请求有利地与在系统总线上发送请求之前与第一组中的像素的写回请求交错。

摘要： In some applications, such as video motion compression processing for example, a request pattern or “stream” of requests for accesses to memory (e.g., DRAM) may have, over a large number of requests, a relatively small number of requests to the same page. Due to the small number of requests to the same page, conventionally sorting to aggregate page hits may not be very effective. Reordering the stream can be used to “bury” or “hide” much of the necessary precharge/activate time, which can have a highly positive impact on overall throughput. For example, separating accesses to different rows of the same bank by at least a predetermined number of clocks can effectively hide the overhead involved in precharging/activating the rows.
摘要翻译： 在一些应用中，例如视频运动压缩处理，例如，对存储器（例如，DRAM）访问的请求的请求模式或“流”可以在大量请求中具有相对较少数量的请求 页。 由于对同一页面的请求数量不多，常规排序以汇总页面命中可能不是很有效。 重新排序流可以用于“埋葬”或“隐藏”大量必要的预充/激活时间，这对整体吞吐量可能产生很大的积极影响。 例如，将对相同存储体的不同行的访问分离至少预定数量的时钟可以有效地隐藏预充电/激活行所涉及的开销。
