  • Publication number: 20240146435
    Abstract: A passive optical network system having a node that is optically coupled to optical line terminals (OLTs), and that is optically coupled to optical network units (ONUs). The node includes at least one fiber link module (FLM), each FLM including an upstream multiplex conversion device (MCD), and a downstream MCD. The upstream MCD receives an upstream optical signal from the ONUs, converts the upstream optical signal to an upstream electrical signal, and transmits a regenerated upstream optical signal to the OLTs. The downstream MCD receives a downstream optical signal from the OLTs, converts the downstream optical signal to a downstream electrical signal, and transmits a regenerated downstream optical signal to the ONUs.

  • Publication number: 20230409793
    Abstract: An article of manufacture includes a medium with instructions that when read and executed by a processor, cause the processor to identify a code stream to be executed by a system-on-a-chip (SoC). The SoC is to include an open standard processor and hardware accelerators implemented in reprogrammable hardware. The processor is to, from the code stream, identify a first portion of the code stream to be executed as software by the open standard processor and a second portion to be executed in the accelerators, compile the first portion into a binary for execution by the open standard processor, and generate a hardware description for the second portion to be implemented by the hardware accelerators. The hardware description and the binary are to exchange data during execution of the code stream.

  • Patent number: 11755082
    Abstract: In IHSs (Information Handling Systems), cooling is provided by increasing the airflow generated by cooling fans. However, unnecessary airflow cooling results in noise and wasted energy. An IHS processor may support faster operating frequencies when cooled below an upper threshold, but these operating frequencies drop at temperatures below a lower threshold. Embodiments provide techniques for calibrating the cooling of an IHS to the thermal characteristics of a specific processor since manufacturing variances result in processors having differing responses to cooling. A turbo frequency supported by a processor is measured at a series of temperature margins that are progressively lower than the processor's specification temperature. A rate of increase in the measured turbo frequencies is determined at each of the temperature margins. A first temperature margin is identified at which the rate of increase in turbo frequencies falls below a threshold. This margin is used in providing airflow cooling.
