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 ...

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 ...

The discussions on exception handling seem endless. Many articles and white papers talk about how to handle exceptions. However, what is missing is an extensible, generic exception-handling framework ...

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 ...

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 ...
