Abstract: Aspects include apparatuses, systems, and methods for hardware acceleration for inline caches in dynamic languages. An inline cache may be initialized for an instance of a dynamic software operation. A call of an initialized instance of the dynamic software operation may be executed by an inline cache hardware accelerator. The inline cache may be checked to determine that its data is current. When the data is current, the initialized instance of the dynamic software operation may be executed using the related inline cache data. When the data is not current, a new inline cache may be initialized for the instance of the dynamic software operation, including the not current data of a previously initialized instance of the dynamic software operation. The inline cache hardware accelerator may include an inline cache memory, a coprocessor, and/or a functional until one an inline cache pipeline connected to a processor pipeline.

Abstract: Systems and methods for adaptively managing registers in an instruction processor are disclosed. The system identifies one or more registers with inoperable cells. An operand manager identifies a set of operable cells within the one or more registers with inoperable cells and determines if a present instruction will use an operand that can be supported by the set of operable cells. When the set of operable cells can support the operand, the operand manager generates an assignment which is communicated to a register file manager.

Abstract: Aspects include computing devices, systems, and methods for implementing scheduling and execution of lightweight kernels as simple tasks directly by a thread without setting up a task structure. A computing device may determine whether a task pointer in a task queue is a simple task pointer for the lightweight kernel. The computing device may schedule a first simple task for the lightweight kernel for execution by the thread. The computing device may retrieve, from an entry of a simple task table, a kernel pointer for the lightweight kernel. The entry in the simple task table may be associated with the simple task pointer. The computing device may directly execute the lightweight kernel as the simple task.

Abstract: A computing device (e.g., a mobile computing device, etc.) may be configured to may be configured to better exploit the concurrency and parallelism enabled by modern multiprocessor architectures by identifying a sequence of tasks via a task dependency controller, commencing execution of a first task in the sequence of tasks, and setting a value of a register so that each remaining task in the sequence of tasks executes after its predecessor task finishes execution without transferring control to a runtime system of the computing device. The task dependency controller may be a hardware component that is shared by the processor cores and/or otherwise configured to transfer control between tasks executing on different processor cores independent of the runtime system and/or without performing the relatively slow and memory-based inter-task, inter-thread or inter-process communications required by conventional solutions.

Abstract: Systems, methods, and devices for executing a function in a dynamically-typed language are described herein. In one aspect, a method includes generating a function selection decision tree based on one or more specializations of a generic function and one or more function inputs via an electronic device. The method further includes selecting one of the specializations or the generic function based on an input type of at least one function input via the electronic device. The method further includes calling the selected specialization or generic function via the electronic device. Another aspect of the subject matter described in the disclosure provides a method of executing a function in a prototype-based dynamically-typed language. The method includes maintaining a list of calls to one or more specializations of the function via the electronic device. The method further includes creating or destroying a specialization of the function via the electronic device. The method further includes updating calls to the created or destroyed specialization via the electronic device. Advantageously in certain embodiments, selection logic overhead can be reduced using criteria that can utilize different weightages for one or more inputs based on heuristics or runtime information.

Abstract: Embodiments include computing devices, apparatus, and methods implemented by the apparatus for accelerating machine learning on a computing device. Raw data may be received in the computing device from a raw data source device. The apparatus may identify key features as two dimensional matrices of the raw data such that the key features are mutually exclusive from each other. The key features may be translated into key feature vectors. The computing device may generate a feature vector from at least one of the key feature vectors. The computing device may receive a first partial output resulting from an execution of a basic linear algebra subprogram (BLAS) operation using the feature vector and a weight factor. The first partial output may be combined with a plurality of partial outputs to produce an output matrix. Receiving the raw data on the computing device may include receiving streaming raw data.

Abstract: Embodiments include computing devices, systems, and methods for task-based handling of repetitive processes in parallel. At least one processor of the computing device, or a specialized hardware controller, may be configured to partition iterations of a repetitive process and assign the partitions to initialized tasks to be executed in parallel by a plurality of processor cores. Upon completing a task, remaining divisible partitions of the repetitive process of ongoing tasks may be subpartitioned and assigned to the ongoing task, and the completed task or a newly initialized task. Information about the iteration space for a repetitive process may be stored in a descriptor table, and status information for all partitions of a repetitive process stored in a status table. Each processor core may have an associated local table that tracks iteration execution of each task, and is synchronized with the status table.
