No.8（2005）15.A Real-time Processor Generation Method for Control Programs

Yuji TAKEDA, Kazumi SAKAMAKI, Takeshi INUI and Hideki MURAKOSHI

We propose a real-time processor generation method for embedded control systems. Recently, it is a problem has developed wherein controllers are developed for a shorter period of time and by fewer hardware quantities in embedded systems, and the responsibility of the controllers is required in the control systems. In the conventional methodologies, the controllers are realized from general CPU, real-time OS, and control programs from the bottom-up. However, their methodologies cannot acquire the controllers having responsibility based on the specifications such as the designs in UML cannot be acquired without changing control programs. Then, we solved these problems by generating the architectures of the processor core from control programs by making use of the reconfigureable device, FPGA. We show that the generation algorithm can generate applicable instruction set of the processor core.
