  • Publication number: 20240113698
    Abstract: A radiofrequency frontend device includes a memory array, which includes a plurality of input lines; a plurality of output lines; and a plurality of impedance devices, each impedance device connecting an input line of the plurality of input lines to an output line of the plurality of output lines, wherein each impedance represents a filter coefficient; wherein the radiofrequency frontend device is configured to provide at each input line of the plurality of input lines a sampled voltage of an analog electric signal, each sampled voltage corresponding to a voltage of the analog electric signal during a respective time period of a plurality of time periods; and when the memory array receives the sampled voltages, the memory array is configured to modify each of the sampled voltages by a respective impedance device of the plurality of impedance devices and sum the modified sampled voltages.

  • Publication number: 20240113725
    Abstract: Systems, apparatuses and methods may provide for technology that includes a capacitor ladder, a plurality of memory cells coupled to the capacitor ladder, the plurality of memory cells to control the capacitor ladder to conduct multi-bit multiply accumulate (MAC) operations during a computation phase, and a successive approximation register (SAR) coupled to the capacitor ladder, the SAR to control the capacitor ladder to digitize results of the multi-bit MAC operations during a digitization phase.

  • Patent number: 11586477
    Abstract: System and method for benchmarking a container orchestration platform in a computing environment uses data contained in a configuration file, which specifies at least one benchmark operation having benchmark actions for container orchestration resource types to be performed in the container orchestration platform, to create a resource manager for each container orchestration resource type specified in the configuration file. Using the created resource managers, a routine for each benchmark action is spawned and executed on container orchestration objects in the container orchestration platform. As the routines are executed, performance metrics are collected and at least some of the collected performance metrics are displayed.
