Abstract: Advances in wireless technologies have resulted in the ability of a 5G communication system to support multiple wireless communication applications. Each of these applications requires special handling in all layers and more so in scheduler and physical layer. The present disclosure presents embodiments of dynamical creating a computation instance with a slice of resources allocated for each scheduling input. Each computation instance may be independently managed, controlled, and customized according to the specific requirements of the corresponding scheduling input. Such a dynamic resource allocation allows large number of slices in PHY layer. Furthermore, when overloading happens, one scheduling inputs may be migrated from one distribution unit (DU) to another DU without interruption for end users during scheduling migration. Accordingly, efficiency and robustness of a 5G communication system may be improved to serve multiple wireless communication applications.

Abstract: System and method embodiments are disclosed to improve radio access network coverage area, increase throughput, and reduce power consumption in user equipment (UE). Downlink (DL) and uplink (UL) are disaggregated in one or more radio units (RUs). A UE receives DL data packets from a DL RU and uploads UL data packets to a UL RU disaggregated from the DL RU. The UL RU couples to a distributed unit (DU) directly or via the DL RU such that an acknowledgment or error message for successful or unsuccessful reception of the UL data packets may be sent back to the UE via the DL RU. The DU may track a UE motion trajectory and re-map UL traffic from one UL RU to another UL RU. Embodiments of DL/UL disaggregation may improve power efficiency and be advantageous for various applications such as internet of things, cyber physical systems, 5G communications, etc.

Abstract: A system and method are provided for evenly distributing central processing unit (CPU) packet processing workloads. The method accepts packets for processing at a port hardware module port interface. The port hardware module supplies the packets to a direct memory access (DMA) engine for storage in system memory. The port hardware module also supplies descriptors to a mailbox. Each descriptor identifies a corresponding packet. The mailbox has a plurality of slots, and loads the descriptors into empty slots. There is a plurality of CPUs, and each CPU fetches descriptors from assigned slots in the mailbox. Then, each CPU processes packets in the system memory in the order in which the associated descriptors are fetched. A load balancing module estimates each CPU workload and reassigns mailbox slots to CPUs in response to unequal CPU workloads.

Abstract: A hardware-based method is provided for allocating shared resources in a system-on-chip (SoC). The SoC includes a plurality of processors and at least one shared resource, such as an input/output (IO) port or a memory. A queue manager (QM) includes a plurality of input first-in first-out memories (FIFOs) and a plurality of output FIFOs. A first application writes a first request to access the shared resource. A first application programming interface (API) loads the first request at a write pointer of a first input FIFO associated with the first processor. A resource allocator reads the first request from a read pointer of the first input FIFO, generates a first reply, and loads the first reply at a write pointer of a first output FIFO associated with the first processor. The first API supplies the first reply, from a read pointer of the first output FIFO, to the first application.

Abstract: An operating system (OS) is provided including a hardware-based task scheduler, with a method for managing OS sourced tasks to be performed by a central processing unit (CPU). An OS, partially enabled as software instructions stored in a computer-readable medium and executed by the CPU, generates CPU tasks. The CPU tasks are buffered in a computer-readable task database memory. CPU task IDs associated with the buffered CPU tasks are enqueued in a CPU queue. Subsequently, the CPU dequeues a first task ID from the CPU queue, and accessing a first CPU task from the task database associated with the first CPU task ID. The CPU delivers the first CPU task to the OS. The OS generates the CPU instructions needed to perform the first CPU task, and sends the CPU instructions to the CPU for performance.

Abstract: A system-on-chip (SoC) is provided with a low power processor to manage power-save mode operations. The SoC has a high-speed group with a high-speed processor, a standby agent, and a governor. In response to inactivity, the governor establishes a power-save mode and deactivates the high-speed group, but not the standby agent. The standby agent monitors SoC input/output (IO) interfaces, and determines the speed requirements associated with a received communication. In response to determining that the communication does not prompt a high-speed SoC operation, the standby agent responds to the communication. Likewise, the standby agent monitors SoC internal events such as housekeeping and timer activity, and the standby performs the tasks if it is determined that the tasks do not require a high-speed SoC operation. Alternatively, if monitored communication or internal event prompts a high-speed SoC operation, the governor activates a member of the high-speed group.

Abstract: A data structure splitting method is provided for processing data using a minimum number of memory accesses. An SoC is provided with a with a central processing unit (CPU), a system memory, an on-chip memory (OCM), and a network interface including an embedded direct memory access (DMA). The network interface accepts a data structure with a header and a payload. The DMA writes the payload in the system memory, and the header in the OCM. The network interface DMA notifies the CPU of the header address in the OCM. The CPU reads the header in the OCM, performs processing instructions, and writes the processed header in the OCM. The CPU sends the address of the processed header in OCM to the network interface DMA. The network interface DMA reads the processed header from the OCM and sends a data structure with the processed header and the payload.
