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 ...
This paper will discuss design practices and guidelines that will maximize the efficiency of interrupts and interrupt handling in an embedded system IC. These practices can result in a smaller code ...
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 ...
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 ...
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 ...
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 ...
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 ...
Interrupts are a major feature of most embedded microcontrollers and effective real time response to interrupts is vital in low power systems that often rely on a ‘run fast then stop’ approach to ...
