Abstract
A method of performing a sequence of related activities in multiple digital processors includes the steps of: executing a portion of a first activity of the sequence in a first processor and then executing an INTERPROCESSOR CALL instruction to a second activity in a second processor; suspending execution of the first activity in response to the CALL and signaling the second processor that the second activity has been called by the first activity; completely executing the second activity in the second processor and then executing an INTERPROCESSOR NEXT instruction to a third activity in a third processor; signaling the third processor in response to the NEXT instruction that the third activity has been called not by the second activity but by the caller of the second activity; and completely executing the third activity in the third processor and, upon completion thereof, signaling the third activity's caller to resume execution of the suspended activity.
