RELTEQ

RELTEQ is an extensible timer management system targeted at resource constrained embedded systems. On top of RELTEQ we have implemented a hierarchical scheduling framework with various servers. The current implementation supports:

• sporadic tasks
• polling, periodic idling, deferrable, and constant bandwith servers
• local Fixed Priority and Earlieas Deadline First schedulers
• global Fixed Priority and Earlieas Deadline First schedulers

RELTEQ is modular, as in it allows to easily turn each of the above features on or off with simple compiler directives. It also provides an intuitive API for extending it with additional primitives.

Download

You can download the latest version of RELTEQ here:

• relteq.zip (version )

The download includes a port of RELTEQ for the uC/OS-II real-time operating system, which was tested within the OpenRISC simulator. Note that, since we are not allowed to distribute the source code of uC/OS-II, it has to be downloaded separately from the Micrium website.

RELTEQ simulator

The RELTEQ simulator is a front-end for RELTEQ, providing a GUI to quickly create and simulate applications consisting of tasks and servers.

Requirements

The simulator does not require any embedded operating systems like uC/OS-II. It does, however, require a *nix operating system with tclsh, gcc and make installed on the path, and the Grasp player.
