  • Software system debugger with distinct interrupt vector maps for debugging and application programs
    Patent number: 5394544
    Abstract: A system for debugging an application program includes a debugging execution unit operated under an operating-system-free environment. The debugging execution unit includes a communication channel, a target processor unit for executing the application program and a first debugging program, and an interrupt vector swapper. The first debugging program includes a first set of input/output procedures for handling debugging communications over the communication channel, and the application program includes a second set of input/output procedures for handling communications over the communication channel associated with execution of the application program. Interrupt signals are generated when the target processor unit receives communications from the host processor unit. The target processor unit communicates with a host processor unit via the communication channel both when executing the application program and when executing the first debugging program.
