The design of DARTS: a dynamic debugger for multiprocessor real-time applications

Abstract

The correctness of execution of a real-time application depends upon the timing properties of the system. The DARTS (debug add on for real-time systems) functions implement a set of debugging functions which have a minimum and predictable influence on the temporal logic of the application. They provide the programmer with crucial information on the temporal logic of the system (direct control flow), they perform watch functions on variables and control the invariant relations which may exist between application and system level objects (indirect dataflow). The workstation is a host target cross development system. Both host and target are single board computers on a VME-bus. The host system runs Unix System V while the targets run MTOS-UX, a multiprocessor real-time operating system.<>
