Integrated processor scheduling for multimedia
[chapter]
1995
Lecture Notes in Computer Science
Preserved Fulltext
We have created a new scheduler that provides integrated processor scheduling for all classes of computational activities. ...
Existing processor schedulers are inadequate in supporting these requirements. ...
Anticipating that processor scheduling based on traditional timesharing would not be suitable for the support of multimedia applications, attempts have been made to adapt real-time schedulers [6] [8] ...
