The kernels are multitasking, allowing multiple applications to execute simultaneously and respond directly to interrupts. With these kernels, there is basically one key time measurement鈥攖he context switch. Whe
hardware interrupt) andsynchronous interrupts(akaexception). The former mayarrive anytime, typically IO interrupts, the latter mayonly arrive after the execution of an instruction, for example when the cpu try to divide a number by 0 or a page fault. So that’s the difference between interrupts...
These interrupts are also known as processor exceptions. 2 Hardware interrupts These interrupts are physically wired into the microcomputer. A special NMI interrupt has the highest priority and cannot be masked out by other interrupts. It is processed during critical hardware events such as a power ...
What’s interesting is if I’m sitting at my desk and I’m absolutely crushing out code, and I’ve got my headphones on, completely in the zone, and somebody walks over to my desk and interrupts me, they’re automatically assuming that what they have to talk about is of higher priorit...

Not sure what represents your IRQ handler as this device has 2 SWT (SWT_A and SWT_B). In your IRQ, do you see the TIF flag for SWT set on module A or B? Then how come this SWT1 ISR is executing not clear for me. Is this ISR used for some other exceptions? Because your ...
Standardized system exception names: This allows OS and middleware to use system exceptions easily without compatibility issues. • Standardized method of header file organization: This makes it easier for users to learn new Cortex microcontroller products and improve software portability. • Common me...
replacing the PSW key with the requesting-program PSW key before making the access and subsequently restoring the called-program PSW key to its original value. Caution must be exercised, however, in handling any resulting protection exceptions since such exceptions may cause the operation to be ...
