Storing in a reserved memory location data indicative of a stack location which stores the entry point of a dynamically loaded file

A method of debugging a computer system connected to a host computer, the computer system having a memory including a reserved storage location designated as a vector, the method comprising:

• dynamically loading into said memory a stack;
• storing in said reserved location information indicative of said stack location;
• dynamically loading a computer file into said memory for use by said computer system;
• and
• storing at a predetermined location in said stack data indicative of an entry point into said dynamically loaded computer file;
• causing an application to run on said computer system
• whereby said application accesses said vector to thereby locate said entry point so that said application calls a subroutine in said computer file.

The combination of a digital signal processor and a host computer, the digital signal processor having a link for connection to said host computer and the host computer being connected to said link, the digital signal processor having a memory including a reserved storage location designated as a vector, wherein the host computer comprises:

• first loading circuitry for dynamically loading a computer file into said memory, thereby determining the location in said memory of an entry point into said dynamically loaded file;
• processor circuitry for forming a stack, said processor circuitry being operative to store at a predetermined location in said stack data indicative of an entry point into said dynamically loaded file;
• second loading circuitry for loading said stack into said memory of said digital signal processor;
• and
• writing circuitry for storing in said reserved location information indicative of said stack location.
