cpu-usage

I have an Amazon EC2 micro instance. I believe that this is 1 core (or 2 for periodic bursts) with 4 CPU's. I'm getting confused with the terminology (ECU vs CPU vs Core) but really I would like to see how busy each CPU is. When I look at top it seems to be showing me just the cores. I want to see if my process is be spread out across the available processors and how busy each is, what is the appropriate command to do this?
