Patents by Inventor Phillip Anthony Carswell

Phillip Anthony Carswell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Cryptographic processing system with programmable function units and method
    Patent number: 6081896
    Abstract: A programmable cryptographic system (100) provides high performance cryptographic processing support for cryptographic algorithms. Two or more independent cryptographic algorithms may be performed at the same time through the processes of background staging and algorithm multi-tasking. A four stage software instruction pipeline and dynamically programmable function units support high performance cryptographic processing performance on the order of 60 mega bits per second (Mbps) aggregate throughput.
    Type: Grant
    Filed: September 2, 1997
    Date of Patent: June 27, 2000
    Assignee: Motorola, Inc.
    Inventors: Kerry Lucille Johns-Vano, David Michael Harrison, Phillip Anthony Carswell, Kevin Thomas Campbell, Dadario McCutcheon
  • Configurable cryptographic processing engine and method
    Patent number: 6026490
    Abstract: A configurable cryptographic processing engine (100) provides high performance cryptographic processing support for symmetric combiner type cryptographic algorithms. As many as two independent cryptographic algorithms may be performed at the same time through the processes of background staging and algorithm multi-tasking. A 3-stage instruction pipeline, dynamically configurable cryptographic co-processor (550), and 32-bit RISC based architecture support high performance cryptographic processing performance on the order of 60 Mbps aggregate throughput.
