  • Patent number: 6789211
    Abstract: To enable a processor connected to a host computer to run programs that are dynamically loaded by the host, a stack is loaded into its memory, and the location of the stack, or information enabling that location to be found are stored in a memory location reserved as a vector. The programs are then dynamically loaded into said memory; and a set location in the stack is used to store the entry point into the dynamically loaded file.
