摘要： A method of allocating a memory to a plurality of concurrent threads is presented. The method includes dynamically determining writer threads each having at least one pending write to the memory; and dynamically allocating respective contiguous blocks in the memory for each of the writer threads. Another method of allocating a memory to a plurality of concurrent threads includes launching the plurality of threads as a plurality of wavefronts, dynamically determining a group of wavefronts each having at least one thread requiring a write to the memory, and dynamically allocating respective contiguous blocks in the memory for each wavefront from the group of wavefronts. A corresponding method of assigning a memory to a plurality of reader threads includes determining a first number corresponding to a number of writer threads having a block allocated in said memory, launching a first number of reader threads, entering a first wavefront of said reader threads from said group of wavefronts to an atomic operation, and assigning a first block in the memory to the first wavefront during the corresponding atomic operation, where the first block is contiguous to a previously allocated block dynamically allocated to another wavefront from said group of wavefronts. Corresponding system embodiments and computer program product embodiments are also presented.
摘要翻译：提出了一种向多个并发线程分配存储器的方法。该方法包括动态地确定写入器线程，每个写入器线程具有至少一个待写入到存储器的并为每个写入器线程动态地分配存储器中的相应连续块。向多个并发线程分配存储器的另一种方法包括：将多个线程作为多个波前发射，动态地确定每组具有至少一个需要对存储器进行写入的线程的波前组，以及动态分配相应的连续块从波浪组的每个波前的记忆。将存储器分配给多个读取器线程的相应方法包括确定与具有在所述存储器中分配的块的写入器线程数相对应的第一数字，启动第一数量的读取器线程，从所述读取器线程的第一波前输入所述波束组合到原子操作，并且在相应的原子操作期间将第一块在存储器中分配给第一波阵面，其中第一块与先前分配的块相邻，所述块先前从所述波阵组中分配给另一波阵面。还提出了相应的系统实施例和计算机程序产品实施例。

摘要： A processor includes a first shader engine and a second shader engine. The first shader engine is configured to process pixel shaders for a first subset of pixels to be displayed on a display device. The second shader engine is configured to process pixel shaders for a second subset of pixels to be displayed on the display device. Both the first and second shader engines are also configured to process general-compute shaders and non-pixel graphics shaders. The processor may also include a level-one (L1) data cache, coupled to and positioned between the first and second shader engines.

摘要： Embodiments for a local data share (LDS) unit are described herein. Embodiments include a co-operative set of threads to load data into shared memory so that the threads can have repeated memory access allowing higher memory bandwidth. In this way, data can be shared between related threads in a cooperative manner by providing a re-use of a locality of data from shared registers. Furthermore, embodiments of the invention allow a cooperative set of threads to fetch data in a partitioned manner so that it is only fetched once into a shared memory that can be repeatedly accessed via a separate low latency path.
摘要翻译：本文描述了本地数据共享（LDS）单元的实施例。实施例包括将数据加载到共享存储器中的线程组合，使得线程可以具有允许更高存储器带宽的重复存储器访问。以这种方式，可以通过提供从共享寄存器重新使用数据的位置，以协作方式在相关线程之间共享数据。此外，本发明的实施例允许协作的线程集合以分区方式获取数据，使得它仅被一次提取到可以经由单独的低等待时间路径重复访问的共享存储器中。

摘要： The present invention provides an efficient state management system for a complex ASIC, and applications thereof. In an embodiment, a computer-based system executes state-dependent processes. The computer-based system includes a command processor (CP) and a plurality of processing blocks. The CP receives commands in a command stream and manages a global state responsive to global context events in the command stream. The plurality of processing blocks receive the commands in the command stream and manage respective block states responsive to block context events in the command stream. Each respective processing block executes a process on data in a data stream based on the global state and the block state of the respective processing block.
