Defining device drivers Discussing the difference between architecture-specific and board-specific drivers Providing several examples of different types of device drivers Most embedded hardware ...

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 ...

As Arm-based infrastructure continues to scale across markets, demands on system components increase. This can mean more interrupts, or signals from hardware/software to a processor to pause a task ...

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 ...

Documents detailing technical aspects of what's thought to be its next-gen Zen 6 CPUs have been posted on AMD's website. The most significant covers AMD's adoption of Intel's so-called 'FRED' ...

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 ...

Normal execution of a given software application is contained within the bounds of one program, or instruction stream. Such execution is provable, as well as traceable. However, system designers and ...

Forward-looking: When AMD releases its Zen 6 processors, the company won't simply iterate on Zen 5 – it will introduce a fundamentally new CPU core architecture, shedding decades of legacy baggage ...

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 ...
