The Perils of Preemptive Multitasking

 Printable PDF

Every commercial RTOS employs a priority-based preemptive scheduler. This despite the fact that real-time systems vary in their requirements and real-time scheduling doesn't have to be so uniform. Multitasking and meeting deadlines is certainly not a one-size-fits-all problem.

Portable Fixed-Width Integers in C

 Printable PDF

For embedded software developers, the most significant improvements to the C programming language made in the ISO C99 standard update are in the new <stdint.h> header file. Learn the typedef names for the new fixed width integer data types, to make hardware interfacing in C easier. And there are other benefits as well

Introduction to Preemptive Multitasking

 Printable PDF

Most real-time operating systems employ preemptive schedulers. This primer on preemption also looks at the kind of multitasking it enables.

Introduction to On-Chip Debug
