In addition to functionality correctness, the system must also meet timing requirement, i.e., to respond before the deadline expires. Examples of real-time and embedded systems include Wireless Sensor Network (WSN), Internet-of-Things (IoT) devices, automobile systems, robots, smart healthcare devices, and smartphones (iOS and Android). Insteand of application design, this course is focused on deep analysis of the Real-Time and Embedded Operating Systems (RTOS) kernels and why they are designed this way. Our lecturing will involve two parts: 1) line-by-line, instruction-by-instruction source code analysis of popular real-time kernels and 2) theoretical foundation of the algorithms used in real-time operating systems. In other words, this course covers both the theory and practice of the system-level issues of real-time embedded systems. Different from commodity OS kernels (Linux and Windows), RTOS kernels are compact and small. In other words, you will have the oppurtunity to trace the source code of and enhance the functionality of an RTOS kernel. Specifically, this course will cover the following topics *Embedded processor architecture CPU register design, memory addressing mode, memory layout, timer hardware, and interrupt handling mechanism *RTOS kernel design CPU scheduling algorithms, memory allocation algorithms, priority management, resource synchronization protocol, deadline handling, process management, and kernel data structures. This course will cover two RTOSes, i.e., uC/OS-2 and FreeRTOS *Real-time scheduling theory Fixed-priority scheduling, deadline-driven scheduling, schedulability analysis, periodic/aperiodic task scheduling, bandwidth servers, resource synchronization protocols, priority inversion management, multiprocessor scheduling algorithms, and case studies.
