		Arm926EJ-S is the entry point processor capable of supporting full
		Operating Systems including Linux, WindowsCE, and Symbian.

		The ARM9E processor family enables single processor solutions for
		microcontroller, DSP and Java applications. The ARM9E family of
		products are DSP-enhanced 32-bit RISC processors, for applications
		requiring a mix of DSP and microcontroller performance. The family
		includes the ARM926EJ-S, ARM946E-S, ARM966E-S, and ARM968E-S
		processor macrocells. 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. The ARM926EJ-S processor also includes ARM Jazelle
		technology which enables the direct execution of Java bytecodes in
		hardware.
