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 ...

Endian format refers to how multibyte variables are stored in a byte-wide memory. In 'big endian' format, the most significant byte is stored in the first byte (lowest address). In 'little endian' ...

The software-interrupt mechanism is one of the oldest parts in the kernel; arguably, the basic design behind it predates Linux itself. Software interrupts can get in the way of other work so, for ...

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 ...

Smartphones have plenty of great capabilities, allowing users to multitask like never before. This is excellent for a consumer, but for the tester it means coming up with new ways of testing. For ...

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 ...

A technical paper titled “CV32RT: Enabling Fast Interrupt and Context Switching for RISC-V Microcontrollers” was published by researchers at ETH Zurich and University of Bologna. “Processors using the ...

If there is an interrupt present then it will trigger the interrupt handler, the handler will stop the present instruction which is processing and save its configuration in a register and load the ...
