Parallel processing time delay method in real-time operating system

摘要

The present invention relates to a time delaying method of a concurrent processing processor in a large-scale real-time multiprocessing system such as a full electronic exchanger.;The present invention can be applied to a central processing unit (MPMA) of a central processing unit (MPMA) including a central processing unit, a storage device, a system status register, a storage management unit, a multifunction peripheral control chip having an input / output device and a timer, A routine for assigning a unique identifier to a process requesting a time delay in processing a time delay request, a routine for converting a time delay demand value requested by an absolute time into a relative time, a routine for converting a delay request time into a millisecond value, A routine for creating a data structure for registering with the manager, and a routine for registering a process requiring a time delay to the time manager and a dispatching routine. In the time manager, a registered process And a routine for calling the scheduler All.
