Embedded system is（66)special computer system which is scalable on both software and（67).

Embedded system is(66)special computer system which is scalable on both software and(67). It can satisfy the strict requirement of functionality,(68), cost, volume, and power consumption of the particular application. With rapid development of(69)design and manufacture, CPUs became cheap. Lots of(70)electronics have embedded CPU and thus became embedded systems. For example, PDAs, cellphones, point-of-sale devices, VCRs, industrial robot control, or even your toasters can be embedded system.

A．cost-oriented

B．applieation-oriented

C．efficiency-oriented

D．consumption-oriented
