	It has been twice an article on IEEE [micro|software] about
	ARM processor.  Articles were written by some guy on
	VLSI-Technology (which produces chips for Olivetti).
	On later of those articles were 'multiply' and 'multiply and
	accumulate' intructions included.

	The chip is used in Acorn Archimedes, which employs 8 MHz
	clock and can achieve 4901 dhrystones.
	We also calculate some mandelbrot pictures with basic and
	512*512 picture with 256 iterations took about 1 hour.
	Quite well for interpretive basic with software floats.
