  • Publication number: 20210232902
    Abstract: A high-endurance, computation-in-memory processor includes a plurality of memory computation modules (MCMs). Each of the MCMs comprise a plurality of memory arrays and a respective module controller to program the plurality of memory arrays to perform mathematical operations on a data set, as well as communicate with other of the MCMs to control a data flow between the MCMs. An inter-module interconnect transports operational data between the MCMs, and communicates with the MCMs to maintain queues storing the operational data during transport between the MCMs. A digital signal processor (DSP) transmits input data to the MCMs and retrieves processed data output by the MCMs.

  • Patent number: 10867239
    Abstract: A co-processor is configured for performing vector matrix multiplication (VMM) to solve computational problems such as partial differential equations (PDEs). An analog Discrete Fourier Transform (DFT) can be implemented by invoking VMM of input signals with Fourier basis functions using analog crossbar arrays. Linear and non-linear PDEs can be solved by implementing spectral PDE solution methods as an alternative to massively discretized finite difference methods, while exploiting inherent parallelism realized through the crossbar arrays. A digital controller interfaces with the crossbar arrays to direct write and read operations to the crossbar arrays.

  • Patent number: 8527003
    Abstract: A system and apparatus including a wireless network architecture that provides broadband data network coverage over an expandable geographic area. A media access control layer is also provided that facilitates access to the broadband wireless network. A high-frequency wireless modem enables high data rate access to the wireless network in a spectrally-efficient manner using SSB modulation. A wideband millimeter-wave antenna includes a cosecant-squared reflector enabling signal propagation between network elements thereby enabling seamless wireless communications. A millimeter-wave polarizer, and a septum polarizer each convert between linear and circular polarization. A cross-shaped horn antenna adapted for circularly polarized signals can also be used in combination with the septum polarizer. A combined horn antenna is fed using a microstrip patch antenna.
