  • Electronic control apparatus with memory validation and method
    Patent number: 6496946
    Abstract: A method and apparatus for confirming the operation of memory (212) operates during periods when the memory is not operating in a standard execution mode. This strategy allows the memory to be checked real-time without impacting normal bandwidth of an associated CPU (200). The method and apparatus guarantees deterministic testing by including circuitry and steps which force bus mastership and, therefore, memory access if the memory is busy for too long a period of time.
    Type: Grant
    Filed: May 10, 1999
    Date of Patent: December 17, 2002
    Assignee: Motorola, Inc.
    Inventors: Ross Bannatyne, Clay E. Merritt, Nancy L. Thomas
