  • Using FPGA partial reconfiguration for codec applications
    Patent number: 9191617
    Abstract: Various embodiments of the present disclosure enable interoperability between multiple codecs of various standards, notwithstanding that the number and type of standards in use at any particular time may vary unpredictably. A control unit, for example, a multipoint control unit (MCU) of a videoconference system, includes a partially reconfigurable programmable logic device (PLD). The PLD may include a reconfigurable region and a non-reconfigurable portion. The non-reconfigurable portion may include logic blocks for performing codec operations that are common across at least two codec standards. A selected subset a number of personas may be instantiated within the reconfigurable region of the PLD, each persona of the selected subset being compatible with at least a portion of the associated codec of at least one communication channel. The MCU selects, from between two or more personas, the selected subset of personas to be used within the reconfigurable region of the PLD.

  • Flexible on-chip datapath interface having first and second component interfaces wherein communication is determined based on a type of credit condition
    Patent number: 8069286
    Abstract: Methods and apparatus are provided for allowing flexible on-chip datapath interfaces on a device. Datapath connections allow data streamlining without any knowledge of channels or packet boundaries. Flexible and modular interface adapters are used to allow component designers to efficiently provide interoperable components without having to adhere to a strict datapath interface specification. Interface adapters from an adapter library are instantiated and configured automatically when two components are connected.

  • Flexible on-chip datapath interface for facilitating communication between first and second interfaces with different interface properties
    Patent number: 7844761
    Abstract: Methods and apparatus are provided for allowing flexible on-chip datapath interfaces on a device. Datapath connections allow data streamlining without any knowledge of channels or packet boundaries. Flexible and modular interface adapters are used to allow component designers to efficiently provide interoperable components without having to adhere to a strict datapath interface specification.

  • JTAG mirroring circuitry and methods
    Patent number: 6961884
    Abstract: The present invention provides a JTAG mirroring circuit that augments the functionality of a JTAG circuit in an existing circuit design. The JTAG circuits include a TAP controller, an instruction register, and a plurality of data registers. The JTAG mirroring circuit of the present invention augments the functionality of pre-existing JTAG circuitry by introducing additional data registers that are multiplexed with data registers in the pre-existing JTAG circuit. Each of the additional data registers may perform functions that are not performed by data registers in the pre-existing JTAG circuit.
