Introduction

Thumb therefore offers a long branch range, powerful arithmetic operations, and a large
address space.
Thumb code is typically 65% of the size of the ARM code, and provides 160% of the
performance of ARM code when running on a processor connected to a 16-bit memory
system. Thumb, therefore, makes the ARM9E-S ideally suited to embedded
applications with restricted memory bandwidth, where code density is important.
The availability of both 16-bit Thumb and 32-bit ARM instruction sets, gives designers
the flexibility to emphasize performance or code size on a subroutine level, according
to the requirements of their applications. For example, critical loops for applications
such as fast interrupts and DSP algorithms can be coded using the full ARM instruction
set, and linked with Thumb code.
