Does Gigabit degrade all ports to 100 megabit if there is a 100 megabit device attached?

Our company is buying some HP Procurve managed gigabit switches to replace some of our core switches. However, we aren't able to upgrade all of our switches from 100Mb to Gigabit switches. I think I know the answer but I'm not exactly sure. If we plug those 100Mb switches (or even a 100Mb device) into those Gigabit switches, will the performance of the entire switch drop to 100Mb or will just that one port work at 100Mb?
