On the lower end of the performance spectrum, many widely available and inexpensive microcontrollers pay for their small pc-board footprints by omitting functions. For example, most low-end processors ...

Embedded systems are deemed real-time if they will suffer a failure when a critical system event cannot be serviced in the required time, and for many embedded systems this time limit is very short.

The scope and capabilities of the Cortex-M0+. The potential advantages of a two-stage vs. three-stage pipeline architecture. How Cortex-M0+ delivers performance and low energy consumption. Cortex-M0+ ...

In a multiprocessor system, a shielded CPU is a CPU dedicated to the activities associated with high-priority real-time tasks. Marking a CPU as shielded allows CPU resources to be reserved for ...

In a System-on Chip(SoC),a general interrupt process works as follows: Interrupt is triggered by a certain system event or interrupt source. Interrupt is detected by system’s peripheral module, which ...

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 ...
