<p>The system has two program storage locations, each storing a respective program, and a program counter (5) that outputs execution address of the programs. A selector (8) changes the address of the counter to another address when it is determined that counter coincides with initial address by a comparator (10). A data bus (10) updates the addresses of the programs stored in two data storage locations. The comparator compares whether or not the counter coincides with one of two addresses. An independent claim is also included for an arithmetic processing method.</p> |
