Abstract
Atomic multiple word writes are provided when emulating a target system that supports atomic multiple word writes on a host system that does not. For each except the last word to be written, a gate flag is read, tested, and locked when it is found unlocked. The words are then written to memory in reverse order, unlocking the gate flags as they are written. In a host system with a longer word size than the target system, the gate flags can be stored in otherwise unused bits in the host system words containing the target system words to be written.
