Aims and objectives of the course. This course deals with current problems in designing complex embedded systems on silicon, also known as "systems on chip". Students will get an understanding of these by studying typical microchip architectures and by modelling these. Following an introductory exercise to get familiar with the tools and the development process, groups of students will design and implement a typical system. Users could then read out sensors, steer actuators, and define control rules via a webpage hosted on another ZYBO board that connects to the peripheral boards via secure TLS channels. The presentation can be downloaded here. In the project, all smart home components should communicate securely over encrypted transmission channels to prevent attackers from taking control over the house. The final demonstrator used ZYBO development boards to implement a trusted microprocessor on an FPGA for performing all security-relevant tasks, to access temperature and light sensors, and to control servomotors. A desktop client was registered at the smart home control unit to access sensor data and change control parameters.

We could have considered eight queues 0. On the other hand, it 0. Hence we model the 0.

Instead, the requesting Some packet service approaches achieve high node queues the request in its egress queue. This strategy can improve system performance That is, system efficiency and throughput and node utilization more than some com- increase as the workload at each queue builds.

However, each Octa- bility, a system using an Octagon architecture gon node must have a queue large enough to requires fewer than 50 packet buffers. Thus, avoid packet loss. Scaling strategy 1. Bridge nodes node y connect adjacent Octagons a and perform hierarchical packet routing. Member nodes attach to only one Octagon node x.

The tables give the maximum distance for Octagon b and crossbar c networks of various sizes. Figure 7a shows queue increases.

Note that a queue size of 25 a scaling strategy that requires two different results in a nominal packet loss of 0. As the name while a queue size of 35 reduces the packet loss implies, bridge nodes connect adjacent probability to 0. If needed, a sys- Octagons and perform hierarchical packet tem designer can enable a zero packet loss guar- routing for example, node y in Figure 7a.

Consider a network at full or near-full capacity, thereby stalling the consisting of eight interconnected Octagons. The Octagon address field of each packet is 6 bits wide: three high-order bits to identify the Scalability local Octagon and three low-order bits to The increasing performance demands of identify the node within the Octagon.

To arrive greater numbers of on-chip components in at these estimates, we assumed the SOC lay- network processors and other SOCs will accel- out in Figure 2a for each octagon.

We extend- erate in the foreseeable future, increasing the ed the layout to the configuration of Figure 2b need for scalable, on-chip communication for crossbars with more than eight nodes. Octagon scales linearly and the crossbar does not because in the crossbar, every node is wired Strategy 1: Low wiring complexity to every other node.

Scaling strategy 2. We extend the Octagon to the multidimensional space by linking corresponding nodes in adja- cent Octagons according to the Octagon configuration a. The table b indicates the increased wiring complexity number of links , and the greater maximum distance needed as the number of connected nodes increases. In this Octagon scaling strategy, Strategy 2: High performance on the other hand, each node requires either For systems in which high performance is three or six wires to its neighbors, resulting in the dominant consideration, we propose a sec- wiring complexity of O cN.

A desktop client was registered at the smart home control unit to access sensor data and change control parameters. As an use case, protected audio was selected. The final demonstrator was built using two ZEDboards, featuring embedded linux including a custom voice-over-IP application. Goal of the project was to design a Linux-based system that allows to play TV video streams over Ethernet. DualShock vibration , multi-player support, etc. There is also a video available here mp4, 19MB.

One board implements Linux on the Xilinx Microblaze processor, the other board implements the Linux running on the Leon 3 processor. The docu can be downloaded here.
