In this presentation we show some examples of combining microcontrollers and FPGA with lower speed serial interfaces and then we show the suggested compact heterogeneous platform configuration where we interface through mini-Flex bus interface a Coldfire controller with a Spartan 6 FPGA.
In this presentation we discuss the developments of the Mari-Sense project and how we use embedded systems with edge processing. Presentation is in Greek.
Presentation of “Flexible and Layered Embedded Firmware through Test Driven Development (TDD)”
Recent years the software industry has developed different methodologies with camps to support them many of them claiming better quality of work and speed. Embedded real-time firmware due to it’s challenges makes adoption of these tools more difficult as we need to test systems interacting with the hardware that have timing constraints. Not all methods work well or there is often the question if the effort is worth the benefit.
In this session we will discuss the application of TDD,
- what is TDD and the difference with unit testing,
- example application of the method,
- how we can model the hardware registers transparently,
- how to tackle challenges porting to different architectures,
- using object oriented techniques for configurability
- the benefits and pitfalls of the method,
The session will be based on actual application of the method on real medium scale bare-bones systems projects.
It is difficult to create a common platform to support completely different applications. In this presentation, we will examine heterogeneous platforms that tightly couple microcontrollers with FPGAs to increase computing capacity, provide flexible interface capabilities, or use other features. We will examine how to set up a link between Coldfire and Spartan 6 devices through mini-flex bus. Bus differences for Kinetis devices will be noted, which shows the advantages of these newer devices and some application examples will be shown.
