Reliable experimental physics DCS Board program execution with COTS TMS570 MCU — •Antonio Lucio, Jano Gebelein, and Udo Kebschull — Infrastructure and Computer Systems in Data Processing, Goethe University Frankfurt, Germany
Given the necessity of a Detector Control Systems Board (DCSB), which shall provide 100 GPIOs, SPI, I2C CAN bus and other interfaces for detector parameter surveillance in experimental physics applications, a new DCSB design is being conceived. Furthermore, under the premise of using low Cost Commercial Off The Shelf (COTS) MCU's, reliable program execution from external redundancy-less memory is necessary. For that purpose the safety MCU TMS570 for automotive applications is examined. EPICS, a Commonly used SCADA for physics experiments, is ported to the MCU and specific MCU's mechanisms are used to apply redundancy to programs executing from external memories with insignificant amount of CPU overhead. Data redundancy reliability from such mechanisms is examined and results are displayed.
