ABSTRACT:
A few inexpensive hardware facilities are incorporated in a tightly synchronized cross checked design. These facilities allow initialization software to quickly bring the two processors to the same state by rapid, repeated resets and execution of the initialization software. The resets are done in a way as to be transparent to the rest of the system and to the end user.
