Abstract: A three-dimensional integrated circuit includes a first die structure having a first geometry. The first die structure 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 three-dimensional integrated circuit includes a second die structure having a second geometry. A stacked portion of the second die structure is aligned with the first region. The three-dimensional integrated circuit includes an additional die structure stacked with the first die structure and the second die structure. The additional die structure has the first geometry or the second geometry.

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 method for manufacturing a three-dimensional integrated circuit includes attaching a first side of a first die to a first carrier wafer. The method includes preparing a second side of the first die to generate a prepared second side of the first die. The method includes attaching the prepared second side of the first die to a second carrier wafer. The method includes removing the first carrier wafer from the first side of the first die to form a transitional three-dimensional integrated circuit. The method includes attaching a third carrier wafer to a first side of the transitional three-dimensional integrated circuit. The method includes attaching a first side of the second die to a second side of the transitional three-dimensional integrated circuit.

Abstract: A technique for accessing memory in an accelerated processing device coupled to stacked memory dies is provided herein. The technique includes receiving a memory access request from an execution unit and identifying whether the memory access request corresponds to memory cells of the stacked dies that are considered local to the execution unit or non-local. For local accesses, the access is made “directly”, that is, without using a bus. A control die coordinates operations for such local accesses, activating particular through-silicon-vias associated with the memory cells that include the data for the access. Non-local accesses are made via a distributed cache fabric and an interconnect bus in the control die. Various other features and details are provided below.

Abstract: A method and apparatus of integrating memory stacks includes providing a first memory die of a first memory technology and a second memory die of a second memory technology. A first logic die is in communication with the first memory die of the first memory technology, and includes a first memory controller including a first memory control function for interpreting requests in accordance with a first protocol for the first memory technology. A second logic die is in communication with the second memory die of the second memory technology and includes a second memory controller including a second memory control function for interpreting requests in accordance with a second protocol for the second memory technology. A memory operation request is received at the first or second memory controller, and the memory operation request is performed in accordance with the associated first memory protocol or the second memory protocol.

Abstract: A method and apparatus for performing inter-lane power management includes de-energizing one or more execution lanes upon a determination that the one or more execution lanes are to be predicated. Energy from the predicated execution lanes is redistributed to one or more active execution lanes.

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: 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.
