  • Patent number: 11455171
    Abstract: A fast and frugal item-state tracking scoreboard circuit is disclosed. The scoreboard maintains per-item partial states across multiple memory circuits, enabling multiple lookups per clock cycle and multiple state updates per clock cycle. In an embodiment a scoreboard is used to schedule instructions in an out-of-order processor. Each clock cycle the scoreboard indicates the busy state of an instruction's registers and may update the busy state of the destination registers of issuing instructions and completing instructions. Applications include register tracking, function-unit tracking, and cache-line state tracking, in embodiments including processor cores (including superscalar, superpipelined, and multithreaded processors), accelerators, memory systems, and networks. In an embodiment, a register-busy scoreboard circuit is implemented using FPGA LUT RAM memory.

  • Patent number: 11298497
    Abstract: A patient interface system for delivering a flow of breathable gas to a user includes a patient interface structure configured to sealingly engage the face of the user. The patient interface system further includes an elbow and connector assembly adapted to receive gases from a flow generator and deliver the gases to the patient interface structure. The elbow and connector assembly includes a ring attached to the patient interface, a sleeve, and an elbow. The ring includes an inner flange, an outer flange separated from the inner flange by a channel, and a plurality of vent slots extending through the inner flange, across the channel, and through the outer flange. The sleeve is configured so that inserting the sleeve into the ring forms a plurality of vent paths for the venting of exhalation gases from an interior of the patient interface to an exterior of the patient interface through the vent slots.

  • Publication number: 20210160177
    Abstract: A configurable directional 2D router for Networks on Chips (NOCs) is disclosed. The router, which may be bufferless, is designed for implementation in programmable logic in FPGAs, and achieves theoretical lower bounds on FPGA resource consumption for various applications. The router employs an FPGA router switch design that consumes only one 6-LUT or 8-input ALM logic cell per router per bit of router link width. A NOC comprising a plurality of routers may be configured as a directional 2D torus, or in diverse ways, network sizes and topologies, data widths, routing functions, performance-energy tradeoffs, and other options. The router and NOC enable feasible FPGA implementation of large integrated systems on chips, interconnecting hundreds of client cores over high bandwidth links, including compute and accelerator cores, industry standard IP cores, DRAM/HBM/HMC channels, PCI Express channels, and 10G/25G/40G/100G/400G networks.
