<p>PURPOSE:To detect an error of a program which accesses a tentative variable that is not present any more. CONSTITUTION:The program is so generated that the addresses of all data access are above the address of a stack painter 5. Comparing the address of the stack painter 5 with an address of data access, the address of correct data access is above the address of the stack pointer 5. A comparator 4 compares the address of the stack pointer 5 with the address of data access at all times and a processor exception is generated when the large/small relation between the addresses is inverted.</p> |
