Debug system for debugging multi-task system

摘要

A debug system and method for facilitating debug of a multi-task system, and a circuit and the like capable of adopting such a debug method are provided. The debug system of the present invention includes: a host computer for executing a debugger program; and a circuit having a complex system constructed thereon including a first multi-task system to be debugged by the debugger program and a second multi-task system which is not a target of debug. The circuit includes a memory having a program stored thereon, and a processor capable of executing the program on the memory. The memory has a first operating system for managing at least one task program in the first multi-task system; and a second operating system for managing the first operating system as a first task program and managing at least one second task program different from the first task program.
