Implementation of a Parallel DSP System Debugger

For the requirement that software debugging is quite difficult for dedicate parallel processing system consisting by multiple digital signal processor (DSP), concept of system-level debugging was proposed. The basic task and method of system-level debugging was discussed based on the hierarchical shared bus hardware structure model. A system level software debugger was designed and implemented with some key technology including hierarchical data structure, static symbol table auto-generation and extendable low level interface. This debugger makes it easy for system and global level debugging of large DSP processing array.
