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 ...

For most UNIX systems, Linux included, device drivers typically divide the work of processing interrupts into two parts or halves. The first part, the top half, is the familiar interrupt handler, ...

Peter Chubb has long been working on a project to move device drivers into user space. Getting drivers out of the kernel, he points out, would have a number of benefits. Faults in drivers (the source ...

Tasklets are a deferred-execution method used within the kernel; they were added in the 2.3 development series as a way for interrupt handlers to schedule work to be done in the very near future.

This application note presents the RX family of microcontrollers on using multiple interrupts. The document includes the specifications, the operation confirmation conditions, the hardware and ...

This application note presents Vector Table Address Switching in a sample code as means for switching the relocatable vector table address and interrupt usage. It presents a brief overview of RX610 ...

This chapter shows how the WdmIo and PHDIo drivers handle interrupts, use Deferred Procedure Calls (DPCs), and catch time-outs. It shows how Read and Write interrupt-driven I/O is started and ...

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 ...
