This paper will discuss design practices and guidelines that will maximize the efficiency of interrupts and interrupt handling in an embedded system IC. These practices can result in a smaller code ...

Vectored interrupts can save up to 20 cycles, significantly decreasing interrupt latency and increasing a processor's capability to manage millions of interrupts per second. “Embedded applications are ...

Interrupts are a major feature of most embedded microcontrollers and effective real time response to interrupts is vital in low power systems that often rely on a ‘run fast then stop’ approach to ...

As an example of a hard real-time scenario, imagine a system where the embedded controller has to respond to incoming sensor data within a specific timespan.

But interrupt latency is just one aspect of a real-time system. Scheduling is another. Here again, there are options with Linux, because the default scheduler isn't always an optimal solution.

Worst-case interrupt latency is 1 µs. The Soft Kernel simulator allows development prior to hardware availability.

When do you need to use a real-time operating system (RTOS) for an embedded project? What does it bring to the table, and what are the costs? Fortunately there are strict technical definitions, whi… ...

The open-source eCos (Embedded Configurable Operating System) is ideal for deeply embedded systems in which memory resources and real-time execution constraints are top design issues. The system ...
