The ARM9E processor family enables single processor solutions for microcontroller,

DSP and Java applications, offering savings in chip area and complexity, power

consumption, and time-to-market. The ARM9E family of products are DSP-enhanced

32-bit RISC processors, well suited for applications requiring a mix of DSP and

microcontroller performance. They include signal processing extensions to enhance

16-bit ﬁxed point performance using a single-cycle 32 x 16 multiply-accumulate (MAC)

unit, and implement the 16-bit Thumb

instruction set giving excellent code density,

maximizing savings on system cost. The ARM926EJ-S processor also includes ARM

Jazelle™ technology which enables the direct execution of Java bytecodes in hardware.

The ARM9 processor family is built around the ARM9TDMI processor and incorporates

the 16-bit Thumb instruction set, which improves code density by as much as 35%.

The ARM9 family’s comprehensive feature set enables developers to implement

leading-edge systems, while delivering considerable savings in chip area, time-to-

market, development costs and power consumption.

NXP ARM9 Architecture Overview

NXP’s LPC3000 and LH7A ARM9

portfolios are based on the

ARM926EJ (ARM9E) and ARM922T

(ARM9) processor families.
