Gearbox Control Unit for the Paddle-shift System: Implementation and Verification of the Hardware and Software

In the dynamic domain of motorsport, the most agile is naturally the victor. A race car can only be as efficient as the systems that control it and here lies the importance of automotive embedded systems which offer precise and quick control over the mechanics of the race car. The Gearbox Control Unit (GCU) for the Paddle-shift System is one...

A Compact, High Precision Position Sensing Embedded System for Fast Steering Mirror

A fast steering tip-tilt mirror is widely used as a pointing and tracking device in aerospace engineering, in laser beam stabilizers and in many other applications. A fast steering mirror has the capability to project light in two-dimensional space. The correct positioning of the mirror is crucial for the device overall operation. In this...

Composable and Predictable Power Management

The functionality of embedded systems is ever growing. The computational power of embedded systems is growing to match this demand, with embedded multiprocessor systems becoming more common. The limitations of embedded systems are not always related to chip size but are commonly due to energy and/or power constraints. While it can be possible to...

Composable Virtual Platforms for Mixed-Criticality Embedded Systems

Recent trends show a steady increase towards concurrently executing more and more applications on a single embedded system. Multi-Processor System-on-Chip (MPSoC) architectures are proposed to allow complex design of embedded systems. This is achieved by integrating as many processing resources as possible on a single chip and therefore enabling...

Control of suction distributions on Boundary layer suction systems for automotive wind tunnels

Wind tunnels are used to study airflows around objects like cars, airplanes and ice-skaters. This is done, simulating the real world, by blowing an airflow over a fixed body. In the real situation an object moves through the air, while in a wind tunnel it is the air that is moving. So a wind tunnel needs to generate an airflow. In this airflow,...

Automated Design of Application-Specific Smart Camera Architectures

Parallel heterogeneous multiprocessor systems are often shunned in embedded system design, not only because of their design complexity but because of the programming burden. Programs for such systems are architecture-dependent: the application developer needs architecture-specific knowledge to implement his algorithms, as each processor has its...
