About this book
This is the Technical Reference Manual (TRM) for the Cortex-R4 and Cortex-R4F processors.
In this book the generic term processor means both the Cortex-R4 and Cortex-R4F processors.
Any differences between the two processors are described where necessary.
Note
The Cortex-R4F processor is a Cortex-R4 processor that includes the optional Floating Point
Unit (FPU) extension, see Product revision information on page 1-24 for more information.
In this book, references to the Cortex-R4 processor also apply to the Cortex-R4F processor,
unless the context makes it clear that this is not the case.
