摘要： A method and apparatus for graphics processing using state and shader management includes at least one state and shader cache coupled to a compiler for compiling a hardware state and shader vector from an abstract state vector. Also included is an abstract state vector register containing the abstract state vector that is provided to the state and shader cache and the compiler. The state and shader cache receives the abstract state vector and determines whether a cache entry for that abstract state vector already exists. If the cache entry exists, the hardware state and shader vector is provided to hardware. If the entry does not exist, the state and shader cache provides a miss signal to the compiler, whereupon the compiler compiles the abstract state vector and generates a hardware state and shader vector. Thereupon the hardware state and shader vector is provided to the hardware.

摘要： A system and method for memory mapping in a multiple video processor (multi VPU) system is described. In various embodiments, rendering tasks are shared among multiple VPUs in parallel to provide improved performance and capability with minimal increased cost. In various embodiments, multiple VPUs in a system access each other's local memories to facilitate cooperative video processing. In one embodiment, each VPU in the system has the local memories of each other VPU mapped to its own graphics aperture relocation table (GART) table to facilitate access via a virtual addressing scheme. Each VPU uses the same virtual addresses for this mapping to other VPU local memories. This allows the driver to send exactly the same write commands to each VPU, including the numeric value of the destination address for operations such as writing rendered data. Thus, unique addresses need not be generated for each VPU.
摘要翻译：描述了在多视频处理器（多VPU）系统中的存储器映射的系统和方法。在各种实施例中，并行地在多个VPU之间共享呈现任务，以最小的成本提供改善的性能和能力。在各种实施例中，系统中的多个VPU访问彼此的本地存储器以促进协作视频处理。在一个实施例中，系统中的每个VPU具有映射到其自己的图形孔径重定位表（GART）表的彼此VPU的本地存储器，以便于经由虚拟寻址方案的访问。每个VPU使用相同的虚拟地址来映射到其他VPU本地存储器。这允许驱动程序向每个VPU发送完全相同的写入命令，包括用于诸如编写渲染数据的操作的目标地址的数值。因此，不需要为每个VPU生成唯一的地址。
