A PC, most of us would say, consists of a complete computer case
with a keyboard and a monitor, all wired up and installed in the
workplace. And yet, the functionality of a PC is increasingly
employed for so-called embedded control systems. Compactness
is the buzzword in this field. US-based ZF Microsystems recently introduced
a chip that reduces all major functions of a PC to a single
component with the size of a credit card.
