First-in/first-out buffer queue management for multiple processes

摘要

A data processing system that includes several ongoing processes that provide input words to a buffer of an independently executing processor, a buffer manager that controls the process access to the buffer and controls the words input by the processes to the buffer that includes an apparatus for regulating the number of words from an executing first process for loading into the buffer, an apparatus for loading the number of words, an apparatus for loading a synchronization word when a second process is to be executed and an apparatus for halting the loading of the first process words and providing for loading of the second process words when the synchronization word is accessed by the independently executing processor.
