Abstract: A processor employs multiple prefetchers at a processor to identify patterns in memory accesses to different memory modules. The memory accesses can include transfers between the memory modules, and the prefetchers can prefetch data directly from one memory module to another based on patterns in the transfers. This allows the processor to efficiently organize data at the memory modules without direct intervention by software or by a processor core, thereby improving processing efficiency.

Abstract: A method, a non-transitory computer readable medium, and a processor for repacking dynamic wavefronts during program code execution on a processing unit, each dynamic wavefront including multiple threads are presented. If a branch instruction is detected, a determination is made whether all wavefronts following a same control path in the program code have reached a compaction point, which is the branch instruction. If no branch instruction is detected in executing the program code, a determination is made whether all wavefronts following the same control path have reached a reconvergence point, which is a beginning of a program code segment to be executed by both a taken branch and a not taken branch from a previous branch instruction. The dynamic wavefronts are repacked with all threads that follow the same control path, if all wavefronts following the same control path have reached the branch instruction or the reconvergence point.

Abstract: An artificial neural network that includes first subnetworks to implement known functions and second subnetworks to implement unknown functions is trained. The first subnetworks are trained separately and in parallel on corresponding known training datasets to determine first parameter values that define the first subnetworks. The first subnetworks are executing on a plurality of processing elements in a processing system. Input values from a network training data set are provided to the artificial neural network including the trained first subnetworks. Error values are generated by comparing output values produced by the artificial neural network to labeled output values of the network training data set. The second subnetworks are trained by back propagating the error values to modify second parameter values that define the second subnetworks without modifying the first parameter values. The first and second parameter values are stored in a storage component.

Abstract: A three-dimensional integrated circuit includes a first die having a first geometry. The first die includes a first region that operates with a first power density and a second region that operates with a second power density. The first power density is less than the second power density. The first die includes first electrical contacts disposed in the first region on a first side of the first die along a periphery of the first die. The three-dimensional integrated circuit includes a second die having a second geometry. The second die includes second electrical contacts disposed on a first side of the second die. A stacked portion of the second die is stacked within the periphery of the first die and an overhang portion of the second die extends beyond the periphery of the first die. The second electrical contacts are aligned with and coupled to the first electrical contacts.

Abstract: A method and apparatus of performing a memory operation includes receiving a memory operation request at a first memory controller that is in communication with a second memory controller. The first memory controller forwards the memory operation request to the second memory controller. Upon receipt of the memory operation request, the second memory controller provides first information or second information depending on a condition of a pseudo-bank of the second memory controller and a type of the memory operation request.

Abstract: A processing device includes a first memory that includes a context buffer. The processing device also includes a processor core to execute threads based on context information stored in registers of the processor core and a memory controller to selectively move a subset of the context information between the context buffer and the registers based on one or more latencies of the threads.

Abstract: A compute unit configured to execute multiple threads in parallel is presented. The compute unit includes one or more single instruction multiple data (SIMD) units and a fetch and decode logic. The SIMD units have differing numbers of arithmetic logic units (ALUs), such that each SIMD unit can execute a different number of threads. The fetch and decode logic is in communication with each of the SIMD units, and is configured to assign the threads to the SIMD units for execution based on such differing numbers of ALUs.
