DOpE - a window server for real-time and embedded systems

N. Feske, H. Hartig
Proceedings. 2003 International Symposium on System-on-Chip (IEEE Cat. No.03EX748)  
A window server used in real-time applications should be able to assure previously agreed-upon redrawing rates for a subset of windows while providing best-effort services to the remaining windows and  ...  A window server used in embedded systems should be small and require only minimal operating system support, for example just threads and address spaces as provided by microkernels.  ...  This facts makes DOpE viable for embedded systems and secure architectures in which the window server belongs to the trusted computing base.  ...
