摘要： A memory module includes a plurality of register files. Each register file is associated with a set of error-correcting code (ECC) bits and ECC check/correct logic that can provide error-correcting functionality, if required. When error-correcting functionality is not required, ECC bits are grouped together to form additional register files, thereby providing additional storage space.

摘要： One embodiment of the present invention sets forth a technique for collecting operands specified by an instruction. As a sequence of instructions is received the operands specified by the instructions are assigned to ports, so that each one of the operands specified by a single instruction is assigned to a different port. Reading of the operands from a multi-bank register file is scheduled by selecting an operand from each one of the different ports to produce an operand read request and ensuring that two or more of the selected operands are not stored in the same bank of the multi-bank register file. The operands specified by the operand read request are read from the multi-bank register file in a single clock cycle. Each instruction is then executed as the operands specified by the instruction are read from the multi-bank register file and collected over one or more clock cycles.

摘要： A computing device detects divergences between threads in a thread group executing on a parallel processing unit. The computing device includes an address divergence unit that identifies a subset of non-divergent threads included in the thread group. The address divergence unit stores instructions related to the subset of non-divergent threads in a multi-issue queue. The address divergence unit causes the instructions related to the subset of non-divergent threads to be retrieved from the multi-issue queue when the parallel processing unit is available. The address divergence unit causes the subset of non-divergent threads to be issued for execution on the parallel processing unit. The address divergence unit repeats the identifying, storing, and causing steps for the remaining threads in the thread group that are not included in the subset of non-divergent threads.

摘要： A method and apparatus provides a mechanism to transform or “morph” Formal verification method assertions so that an assertion defined in one Design Under Test (DUT) can be replicated, or derived, to propagate into other related DUTs. Using the method and apparatus of the present invention, individual DUTs can better leverage assertions defined independently in other DUT environments. This, in turn, provides for greater productivity and a faster, smoother verification process-using Formal and Assertion Based Verification methods.

摘要： An address divergence unit detects divergence between threads in a thread group and then separates those threads into a subset of non-divergent threads and a subset of divergent threads. In one embodiment, the address divergence unit causes instructions associated with the subset of non-divergent threads to be issued for execution on a parallel processing unit, while causing the instructions associated with the subset of divergent threads to be re-fetched and re-issued for execution.

摘要： One embodiment of the present invention sets forth a technique that provides an efficient way to retrieve operands from a register file. Specifically, the instruction dispatch unit receives one or more instructions, each of which includes one or more operands. Collectively, the operands are organized into one or more operand groups from which a shaped access may be formed. The operands are retrieved from the register file and stored in a collector. Once all operands are read and collected in the collector, the instruction dispatch unit transmits the instructions and corresponding operands to functional units within the streaming multiprocessor for execution. One advantage of the present invention is that multiple operands are retrieved from the register file in a single register access operation without resource conflict. Performance in retrieving operands from the register file is improved by forming shaped accesses that efficiently retrieve operands exhibiting recognized memory access patterns.
摘要翻译：本发明的一个实施例提出了提供从寄存器文件中检索操作数的有效方式的技术。具体地，指令分派单元接收一个或多个指令，每个指令包括一个或多个操作数。总的来说，操作数被组织成一个或多个操作数组，从中可以形成成形的访问。操作数从寄存器文件中检索并存储在收集器中。一旦所有操作数被读取并收集在收集器中，指令分派单元将指令和相应的操作数发送到流多处理器内的功能单元以供执行。本发明的一个优点是在没有资源冲突的情况下，在单个寄存器访问操作中从寄存器文件中检索多个操作数。通过形成有效地检索具有公认的存储器访问模式的操作数的形状访问来改进从寄存器文件中检索操作数的性能。
