Syllabus
Unit 1 Introduction to QNX OS Architecture: Overview of QNX OS architecture: microkernel, process manager, and standards. Protected address spaces, process/thread model, and scheduling. Introduction to inter-process communication (IPC) and synchronization. Resource managers and shared objects. Unit 2 Processes, Threads, and Synchronization: Process management: creation, termination, and memory protection. Thread management: creation, termination, and synchronization. Synchronization techniques: mutexes, semaphores, and condition variables. Hands-on exercises: process/thread creation and synchronization. Unit 3Inter-Process Communication (IPC): Overview of IPC methods in QNX: message passing, pulses, and shared memory. Comparing IPC methods: advantages and disadvantages. Practical implementation of IPC in QNX. Hands-on exercises: message passing and shared memory. Unit 4Hardware Programming and Timing: Hardware access methods: IO-mapped and memory-mapped IO. Interrupt handling and DMA-safe memory allocation. Timing architecture: periodic timing, one-shot timing, and timeouts. Hands-on exercises: interrupt handling and timing mechanisms. Unit 5Building and Configuring QNX Boot/OS Images: Overview of QNX boot/OS image structure. Components of a boot image: startup code, kernel, drivers, and scripts. Building and loading boot images onto target hardware. Introduction to resource managers and their implementation.
Experiments
Lab Experiments1. QNX configuration and application development using QNX Momentics IDE. 2. Process and thread creation, management, and synchronization. 3.
