System Architectures

The main goal of the subject to present the main modules of the design platform of embedded system architectures. The components are discussed in an application oriented way, with comparison and selection information. The focus is on the interfacing to the physical processes, and other information systems. The first part is introducing the signal conditioning and input stages, including the programmable gain, A/D and isolating stages. The course presents the typical sensor I/O solutions and the necessary interfacing circuits, including the intelligent TEDS solutions also. The main part of the lecture is devoted to the System on a Chip (SoC) architectures and their composition. A small review of the main controller architectures presents the most important families, like RISC, DSP, VLIW type of processors. The on chip communication bus architecture are evaluated deeply, including the AMBA, CoreConnect and Wishbone systems. The concept of NoC is demonstrated by real word application examples. The wireless sensor node systems are analyzed from the communication and energy efficiency point. All components and processes are evaluated from the power requirement point of view. The final part of the subject is introduces the modern test and development technologies, including the in system debugging methodologies.
