Whether an embedded system is a handheld Internet device, a telephone switch, or a complex aircraft control setup, the real-time operating system (RTOS) running it must guarantee uninterrupted service ...

The sequence of importance assigned to interrupts. If two interrupts occur simultaneously, the interrupt with the higher priority is serviced first. In some systems, a higher-priority interrupt can ...

An increasing number of multi-threaded embedded applications want to leverage multicore designs. Symmetric Multiprocessing (SMP) RTOS provides automatic load balancing of multiple threads in a ...

What’s the biggest difference between writing code for your big computer and a microcontroller? OK, the memory and limited resources, sure. But we were thinking more about the need to directly ...

A priority interrupt controller is a hardware designed chip which acts as an overall system manager to efficiently handle the multiple interrupts that tend to occur from the varied number of ...

As a fully preemptive kernel, SST must ensure that at all times the CPU executes the highest-priority task that's ready to run. Fortunately, only two scenarios can lead to readying a higher-priority ...

Many DSP systems are multirate systems. This means there are multiple tasks in the DSP system running at different periodic rates. Multirate DSP systems can be managed using nonpreemptive as well as ...
