    • This disclosure describes techniques for selectively activating a resume check operation in a single instruction, multiple data (SIMD) processing system. A processor is described that is configured to selectively enable or disable a resume check operation for a particular instruction based on information included in the instruction that indicates whether a resume check operation is to be performed for the instruction. A compiler is also described that is configured to generate compiled code which, when executed, causes a resume check operation to be selectively enabled or disabled for particular instructions. The compiled code may include one or more instructions that each specify whether a resume check operation is to be performed for the respective instruction. The techniques of this disclosure may be used to reduce the power consumption of and/or improve the performance of a SIMD system that utilizes a resume check operation to manage the reactivation of deactivated threads.
    • 本公开描述了用于在单个指令,多数据(SIMD)处理系统中选择性地激活恢复检查操作的技术。 描述了一种处理器,其被配置为基于指示是否对该指令执行恢复检查操作的指令中的信息选择性地启用或禁用特定指令的恢复检查操作。 还描述了一种编译器,其被配置为生成编译代码,其在被执行时导致对特定指令选择性地启用或禁用恢复检查操作。 编译代码可以包括一个或多个指令,每个指令指定是否对相应的指令执行恢复检查操作。 本公开的技术可以用于减少利用恢复检查操作来管理停用线程的重新激活的SIMD系统的功耗和/或提高性能。

    • A method and device for performing and processing user-defined clipping in object space to reduce the number of computations needed for the clipping operation. The method and device also combine the modelview transformation of the vertex coordinates with projection transform. The user-defined clipping in object space provides a higher performance and less power consumption by avoiding generation of eye coordinates if there is no lighting. The device includes a driver for the user-defined clipping in the object space to perform dual mode user-defined clipping in object space when a lighting function is disabled and in eye space when the lighting function is enabled.
    • 一种用于在对象空间中执行和处理用户定义的限幅以减少剪切操作所需的计算次数的方法和装置。 该方法和装置还将顶点坐标的modelview变换与投影变换相结合。 对象空间中的用户定义的剪辑通过避免在没有照明的情况下产生眼睛坐标来提供更高的性能和更低的功耗。 该设备包括用于在对象空间中的用户定义的剪切的驱动器,以在禁用照明功能时在对象空间中执行双模式用户定义的剪辑,并且在启用照明功能时在眼睛空间中执行双模式用户定义的剪辑。
