Rapid-Prototyping of Embedded Systems via Reprogrammable Devices
Abstract:
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.
