Rapid-Prototyping of Embedded Systems via Reprogrammable Devices

This paper describes a flexible board-level rapid-prototyping environment for embedded control applications. The environment is based on an APTIX board populated by Xilinx FPGA devices, a 68hc11 emulator, and APTIX programmable interconnect devices. Given a design consisting of logic and of software running on a micro-controller that implement a set of tasks, the prototype is obtained by programming the FPGA devices, the micro-controller emulator and the APTIX devices. This environment being based on programmable devices offers the flexibility to perform engineering changes, the performance needed to validate complex systems and the hardware set up for field tests. The key point in our approach is the use of results of our previous research on software and hardware synthesis as well as on some commercial tools to provide the designer with fast programming data from a high level description of the algorithms to be implemented. We demonstrate the effectiveness of the approach by showing a close-to real-life example from the automotive world.
