DISDEB: an interactive high-level debugging system for a multi-microprocessor system

This paper describes the architecture of the interactive debugging system DISDEB, which is intended to debug programs on a multi-microprocessor system constituting a node of the Selenia Mara architecture. DISDEB requires neither changes in or additions to the code produced by the compiler nor heavy modifications to the operating system Kernel. Moreover, the use of ad hoc hardware provided with autonomous processing power allows the user to monitor and control the execution of both concurrent and distributed processes and their interactions, while, in most cases, maintaining the real-time operation of the target Mara system
