摘要： System and method for reserving a memory space for multithreaded processing is described. Memory space within a memory resource is allocated responsive to thread type. Examples of thread types for graphics processing include primitive, vertex and fragment types. Memory space allocated may be of a predetermined size for a thread type. Memory locations within a first memory space may be interleaved with memory locations within a second memory space.

To accomplish this, vertex data is received in the form of vectors after which vector operations are performed on the vector vertex data. Next, scalar operations may be executed on an output of the vector operations, thereby rendering vertex data in the form of scalars.

摘要： One embodiment of the present invention sets forth a technique for scheduling thread execution in a multi-threaded processing environment. A two-level scheduler maintains a small set of active threads called strands to hide function unit pipeline latency and local memory access latency. The strands are a sub-set of a larger set of pending threads that is also maintained by the two-leveler scheduler. Pending threads are promoted to strands and strands are demoted to pending threads based on latency characteristics. The two-level scheduler selects strands for execution based on strand state. The longer latency of the pending threads is hidden by selecting strands for execution. When the latency for a pending thread is expired, the pending thread may be promoted to a strand and begin (or resume) execution. When a strand encounters a latency event, the strand may be demoted to a pending thread while the latency is incurred.
摘要翻译：本发明的一个实施例提出了一种用于在多线程处理环境中调度线程执行的技术。一个两级调度程序维护一组称为线索的活动线程，以隐藏功能单元流水线延迟和本地存储器访问延迟。这些链是一组更大的待处理线程的子集，其也由二级调度器维护。等待线程被提升为线索，并且基于延迟特性将线降级到等待线程。两级调度器基于线状态来选择用于执行的线。通过选择要执行的链来隐藏待处理线程的延迟更长。当待处理线程的等待时间到期时，挂起的线程可以被提升为一个线并开始（或恢复）执行。当一条线遇到一个延迟事件时，该链可以被降级到等待线程，同时发生延迟。

摘要： Methods and apparatus for source operand collector caching. In one embodiment, a processor includes a register file that may be coupled to storage elements (i.e., an operand collector) that provide inputs to the datapath of the processor core for executing an instruction. In order to reduce bandwidth between the register file and the operand collector, operands may be cached and reused in subsequent instructions. A scheduling unit maintains a cache table for monitoring which register values are currently stored in the operand collector. The scheduling unit may also configure the operand collector to select the particular storage elements that are coupled to the inputs to the datapath for a given instruction.

摘要： An embodiment of a computing system is configured to process data using a multithreaded SIMD architecture that includes heterogeneous processing engines to execute a program. The program is constructed of various program instructions. A first type of the program instructions can only be executed by a first type of processing engine and a third type of program instructions can only be executed by a second type of processing engine. A second type of program instructions can be executed by the first and the second type of processing engines. An assignment unit may be configured to dynamically determine which of the two processing engines executes any program instructions of the second type in order to balance the workload between the heterogeneous processing engines.
