چکیده

We show that, for a large class of hard real-time systems , any object with consensus number P in Herlihy's wait-free hierarchy is universal for any number of tasks executing on P processors. These results exploit characteristics of priority-based schedulers common to most hard real-time systems. An important special case of this result is that, for hard real-time applications on uniprocessors, reads and writes are universal. Thus, Herlihy's hierarchy collapses for such applications.

cient Object Sharing in Real - Time SystemsJames

We show that, by rejecting a number of conventional assumptions about real-time object sharing, it is possible to develop and implement eecient object-sharing mechanisms on uniprocessors that do not require complex kernel and hardware support. Chief among the assumptions we reject is that objects should be implemented using lock-based protocols. As explained herein, the use of locking in real-t...

Real - Time Object Sharing with Minimal System

We show that any object with consensus number P in Herlihy's wait-free hierarchy is universal in a hard real-time system consisting of any number of tasks on P processors. An important special case of this result is that, for hard real-time applications on uniprocessors, reads and writes are universal. Thus, Herlihy's hierarchy collapses for such applications. We also show that, by exploiting t...

ساختار دهی آنی داده‌‌های مکانی ورودی GIS با تأکید بر عارضه راه

An important issue in implementation of a GIS system is preparation of data to be entered in GIS. To produce spatial data for GIS using photogrammetric techniques, conventional method is to apply photogrammetric and GIS systems individually (off-line procedure). This approach is costly, time consuming and somehow unreliable due to the fact that 3D photogrammetric model is not available at the ...

DOpE — a Window Server for Real - Time and Embedded Systems — Extended

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 operations such as moving windows. 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 provid...
