EXCEPTION PROCESSOR USED FOR CONTROL OF DEBUGGING DEVICE, EXCEPTION PROCESSING METHOD, EXCEPTION PROCESSING PROGRAM, AND TELEVISION AND CELLPHONE INCORPORATED WITH THE EXCEPTION PROCESSOR

摘要

PPROBLEM TO BE SOLVED: To automatically start a debugger in a state just before execution of an instruction having caused an exception by unauthorized processing without setting a break point in advance. PSOLUTION: A computer executing a program that is a target of debugging work analyzes the cause causing an exception phenomenon to the computer. When the cause is that the instruction stored in a memory space tries to make the computer execute the unauthorized processing, the computer rewrites the instruction by a debugger-starting instruction, selects a task to be executed based on a state of each task and performs a changeover to it, or resumes processing suspended by the occurrence of the exception phenomenon. When the computer executes the debugger-starting instruction, the debugger detects it and starts. PCOPYRIGHT: (C)2009,JPO&INPIT
