Patents Assigned to Virtual Computer Corporation
  • Patent number: 6289440
    Abstract: A virtual network consists of many distributed virtual computers interconnected over a communication network of individual links, such as optical fibers or electrical conductors, for example. Each distributed virtual computer has at least two ports connected over respective links to other respective distributed virtual computers on the network. Each distributed virtual computer is connected to or resident within its own host, each host typically being a conventional computer such as a personal computer or a work station, for example, although at least one of the hosts may itself be another virtual computer. Each distributed virtual computer has reconfigurable logic elements such as an FPGA or an array of FPGAs.

  • Patent number: 6178494
    Abstract: A method is disclosed for integrating a field programmable gate array (FPGA) with a microprocessor to form a single, multi-chip or stacked, hybrid processor module. The method includes the identification and parallel routing of selected I/O pins of the FPGA and microprocessor. The method further includes the identification and routing of control pins of the FPGA and microprocessor to a controller, and, the establishment of an interface between the controller, the FPGA and the microprocessor in order to develop a processor module for coordinated processing of data utilizing both the FPGA and microprocessor resources.

  • Patent number: 5684980
    Abstract: An array of FPGAs change their configurations successively during performance of successive user-defined algorithms. Adjacent FPGAs are connected through external field programmable interconnection devices (FPINs) or cross-bar switches. The array includes a processor-like device capable of performing the computations necessary to reconfigure the FPGAs in the array in accordance with the next algorithm to be performed. Preferably, this processor-like device is itself a "control" array of interconnected FPGAs which have been configured to emulate a selected microprocessor architecture which accepts user-defined primitives corresponding to an algorithm to be performed or a logic architecture to be emulated and reconfigure the FPGAs and the FPINs accordingly.
