The last part of the Embedded Systems programming discuss about interrupt processing and the alternative process of polling. It briefly describes interrupts and polling, as well as the interrupt ...

Performance is a topic that never strays far from the mind of most embedded systems developers. However, relatively speaking, many of us have it easy. We develop soft real-time systems in which a few ...

After introducing interrupts and the foreground/background architecture, I am finally ready to tackle the concept of a Real-Time Operating System (RTOS). In this first lesson on RTOS (commonly ...

Exceptions and interrupts are part of a mechanism provided by the majority of embedded processor architectures to allow for the disruption of the processor s normal execution path. This disruption can ...

Heterogeneous multiprocessor (HMP) systems, using functionally asymmetric compute elements, such as application processors and microcontrollers integrated within the same SoCs, are now used ...

Just as you can often treat device registers as a memory-mapped struct, you can treat an interrupt vector as a memory-mapped array. In my last column, I suggested that you use casts sparingly and with ...
