Understanding RISC‑V traps is essential for Chip Designers building RISC‑V CPUs, microcontrollers, and complex SoCs. It’s equally important for Embedded Engineers who develop and debug software stacks ...

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, ...

What is an exception handler? An exception handler is code that stipulates what a program will do when an anomalous or exceptional event occurs and disrupts the normal flow of that program's ...

A computer cannot meet its requirements unless it communicates with its external devices. An interrupt is a communication gateway between the device and a processor. The allocation of an interrupt ...

Callbacks are references to executable code that higher levels of software pass into a function. These callbacks have the ability to greatly increase the portability and reuse of embedded software, ...

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 ...

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 ...
