This paper presents a uniquely integrated environment where a control system is modeled, simulated and implemented in real time requiring no coding, no compiling nor embedding for multiple test rigs. The novel hardware architecture simultaneously configures itself according to the contents of a visual configuration editor (VCE) that is put together by the user utilizing graphical representations of basic building blocks called primitives. Similar to an analog computer, as the user builds the VCE model, the “code is simultaneously compiled and embedded” into the target DSP processor/s as easy as dragging and dropping primitives from various libraries into the VCE and connecting them. Similarly DSP processors within the hardware network are visually available to the user to be dropped into the VCE creating a distributed multi-processor control environment. The execution of multiple DSPs take place simultaneously reaching 25.6 kHz loop rates and 200 kz sampling rates. The execution order as well as the processor ownership of the primitives are visible in the VCE and can easily be modified. The system operation is demonstrated in a single channel test rig using Auto-PID parameter estimation problem as a case study.
