One aspect of the invention relates to a method useful in a multiprocessor syste m for operating a processor. In one version of the invention, the method includes the steps of storing halt signature data in a register on the processor, the halt signatur e data being representative of whether the processor is in a halt state, storing start addres s data in memory which is accessible by the processor, executing an interruptible spin loo p with the processor, and comparing the halt signature data with a predetermined halt signa ture to determine whether the processor is in a halt state when an interrupt is received and reading the start address data from memory to determine whether there is a reque st to start if the processor is in a halt state.
