AN3129
Application note
Real-time performance using FIQ interrupt handling
in SPEAr MPUs

Introduction
This application note provides information for software developers on how to use the (FIQ)
(fast interrupt request) mechanism with Linux in the SPEAr embedded MPU family.
It is divided into four sections:
Section 1 describes the interrupt logic on SPEAr platform.
Section 2 provides a detailed introduction to the FIQ interrupt handling hardware
