20110072243 | Unified Collector Structure for Multi-Bank Register File - 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.

20130117541 | SPECULATIVE EXECUTION AND ROLLBACK - One embodiment of the present invention sets forth a technique for speculatively issuing instructions to allow a processing pipeline to continue to process some instructions during rollback of other instructions. A scheduler circuit issues instructions for execution assuming that, several cycles later, when the instructions reach multithreaded execution units, that dependencies between the instructions will be resolved, resources will be available, operand data will be available, and other conditions will not prevent execution of the instructions. When a rollback condition exists at the point of execution for an instruction for a particular thread group, the instruction is not dispatched to the multithreaded execution units. However, other instructions issued by the scheduler circuit for execution by different thread groups, and for which a rollback condition does not exist, are executed by the multithreaded execution units. The instruction incurring the rollback condition is reissued after the rollback condition no longer exists. | 05-09-2013 |
20130145124 | SYSTEM AND METHOD FOR PERFORMING SHAPED MEMORY ACCESS OPERATIONS - 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. | 06-06-2013 |
20130166877 | SHAPED REGISTER FILE READS - One embodiment of the present invention sets forth a technique for performing a shaped access of a register file that includes a set of N registers, wherein N is greater than or equal to two. The technique involves, for at least one thread included in a group of threads, receiving a request to access a first amount of data from each register in the set of N registers, and configuring a crossbar to allow the at least one thread to access the first amount of data from each register in the set of N registers. | 06-27-2013 |
20130179662 | Method and System for Resolving Thread Divergences - 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. | 07-11-2013 |
20140164743 | REORDERING BUFFER FOR MEMORY ACCESS LOCALITY - Systems and methods for scheduling instructions for execution on a multi-core processor reorder the execution of different threads to ensure that instructions specified as having localized memory access behavior are executed over one or more sequential clock cycles to benefit from memory access locality. At compile time, code sequences including memory access instructions that may be localized are delineated into separate batches. A scheduling unit ensures that multiple parallel threads are processed over one or more sequential scheduling cycles to execute the batched instructions. The scheduling unit waits to schedule execution of instructions that are not included in the particular batch until execution of the batched instructions is done so that memory access locality is maintained for the particular batch. In between the separate batches, instructions that are not included in a batch are scheduled so that threads executing non-batched instructions are also processed and not starved. | 06-12-2014 |
20150089202 | SYSTEM, METHOD, AND COMPUTER PROGRAM PRODUCT FOR IMPLEMENTING MULTI-CYCLE REGISTER FILE BYPASS - A system, method, and computer program product are provided for implementing a multi-cycle register file bypass mechanism. The method includes the steps of receiving a set of control bits, combining the set of control bits with a set of valid bits associated with previously issued instructions, and enabling a bypass path for each thread based on the set of control bits and the set of valid bits. Each valid bit in the set of valid bits indicates whether execution of an instruction of the previously issued instructions was enabled for a thread in a thread block. | 03-26-2015 |
20150113538 | HIERARCHICAL STAGING AREAS FOR SCHEDULING THREADS FOR EXECUTION - One embodiment of the present invention is a computer-implemented method for scheduling a thread group for execution on a processing engine that includes identifying a first thread group included in a first set of thread groups that can be issued for execution on the processing engine, where the first thread group includes one or more threads. The method also includes transferring the first thread group from the first set of thread groups to a second set of thread groups, allocating hardware resources to the first thread group, and selecting the first thread group from the second set of thread groups for execution on the processing engine. One advantage of the disclosed technique is that a scheduler only allocates limited hardware resources to thread groups that are, in fact, ready to be issued for execution, thereby conserving those resources in a manner that is generally more efficient than conventional techniques. | 04-23-2015 |
20150193272 | SYSTEM AND PROCESSOR THAT INCLUDE AN IMPLEMENTATION OF DECOUPLED PIPELINES - A system and apparatus are provided that include an implementation for decoupled pipelines. The apparatus includes a scheduler configured to issue instructions to one or more functional units and a functional unit coupled to a queue having a number of slots for storing instructions. The instructions issued to the functional unit are stored in the queue until the functional unit is available to process the instructions. | 07-09-2015 |
20150220341 | SYSTEM, METHOD, AND COMPUTER PROGRAM PRODUCT FOR IMPLEMENTING SOFTWARE-BASED SCOREBOARDING - A system, method, and computer program product are provided for implementing a software-based scoreboarding mechanism. The method includes the steps of receiving a dependency barrier instruction that includes an immediate value and an identifier corresponding to a first register and, based on a comparison of the immediate value to the value stored in the first register, dispatching a subsequent instruction to at least a first processing unit of two or more processing units. | 08-06-2015 |
