Abstract

Process switch operations common in multiprogramming environments in commercially available data processors, are carried out faster herein by providing a decision-making capability for determining whether only a subset or all of the usually saved data actually is to be saved each time a process switch operation is called for. Both hardware and software implementations are disclosed.
