摘要： A system and method for providing antialiased memory access includes receiving a request to access a memory address. The memory address is examined to determine if the memory address is within a virtual frame buffer. If the memory address is within a virtual frame buffer then the memory address is transformed into one or more physical addresses within a frame buffer that is utilized for antialiasing. The frame buffer may be a single memory space containing subpixel information corresponding to pixels of the virtual frame buffer. Subpixels located at the physical addresses within the frame buffer are then accessed. The disclosed invention provides for direct access by a software application.

摘要： Systems and methods for determining a compression tag state prior to memory client arbitration may reduce the latency for memory accesses. A compression tag is associated with each portion of a surface stored in memory and indicates whether or not the data stored in each portion is compressed or not. A client uses the compression tags to construct memory access requests and the size of each request is based on whether or not the portion of the surface to be accessed is compressed or not. When multiple clients access the same surface the compression tag reads are interlocked with the pending memory access requests to ensure that the compression tags provided to each client are accurate. This mechanism allows for memory bandwidth optimizations including reordering memory access requests for efficient access.

摘要： Techniques and systems for dynamic binning, in which a stream of requests to access a memory is sorted into a reordered stream that enables efficient access of the memory. A page stream sorter can group requests to access a memory in a manner that results in some “locality” in the stream of requests issued from the page stream sorter to memory, such that as few pages as possible in the same bank are accessed and/or a number of page switches needed is minimized.

摘要： Efficient memory management can be performed using a computer system that includes a client which requests access to a memory, a memory interface coupled to the client and to the memory, wherein the memory interface comprises an arbiter to arbitrate requests received from the client to access data stored in the memory, a look ahead structure for managing the memory, a request queue for queuing memory access requests, and wherein the look ahead structure is located before the arbiter so that the look ahead structure communicates with the memory through the arbiter. Efficient memory management can also be performed by sending a memory access request from a client to a look ahead structure and to a request queue, wherein the look ahead structure comprises a row bank direction queue and a tiering logic, checking state of memory being requested using the tiering logic, prioritizing memory requests according to the memory state, selecting a location to be precharged with a precharge arbiter, selecting a location to be activated using an activate arbiter, selecting a location to read or write using a read/write arbiter, and precharging, activating and reading or writing according the selections according to availability of the memory.
