DEVICE AND METHOD FOR PROGRAM DEBUGGING

PURPOSE: To provide a device and a method for program debugging capable of executing debug by specifying clearly a state when a CPU in which an error has occurred stops and a program stopping position when an error has occurred in each CPU. CONSTITUTION: This device comprises an exceptional stack frame generating means 11 which generates a stack frame to perform the exceptional processing of an error, an exceptional stack frame judging means 131 which judges the format of a generated exceptional stack frame, an exceptional stack data transfer means 151 which transfers exceptional stack data to a memory area corresponding to the format in the common memory area of each CPU based on a judged format, an error flag judging means 132 which judges the error flag of the CPU, an error information transfer means 152 which transfers error information to a specific memory area in the common memory area based on the above judgement, and an error information processing means 17 which displays transferred error information and executes the debug.
