Discussion of principles, methodologies, and tools for designing real-time computing systems and control software for embedded systems and industrial applications.
Introduction to real-time systems
Embedded computing systems. Computing with temporal constraints.
Real-time systems classification and relevant parameters.
A reference model for real-time computing.
Aperiodic task scheduling.
The cyclic executive approach for periodic tasks.
Priority-driven scheduling of periodic tasks.
Priority-driven scheduling of mixed aperiodic, sporadic, and periodic tasks.
Rate-monotonic and EDF scheduling algorithms.
Shared resources access control policies. Priority inversion management.
Operating systems and multithreaded programming
Real-time computing support in modern, general-purpose operating systems.
The POSIX standard: Threads and processes. Thread synchronization. Signals. IPC mechanisms. Scheduling. Time manangement. Memory management. I/O management.
Patterns for real-time systems programming.
Dedicated real-time operating systems.
Middleware for distributed real-time computing systems.
Laboratory classes exercising multithreading and real-time features in Solaris, Linux, and the POSIX library. Multithreading and real-time programming exercises.
Exam consists of three parts: POSIX thread programming assignment, written test, oral discussion. The oral discussion must be the final part and requires prior approval of both the programming assignment and the written test.
