Sure can:
Cisco's CEF techonology page:
http://www.cisco.com/en/US/tech/tk827/tk831/tk102/tsd_technology_support_sub-protocol_home.html
Circa IOS 12.0 CEF overview:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/switch_c/xcprt2/xccef.htm
In a nutshell: CEF is a method of building a Forwarding Table in RAM (and later, on individual cards which support it (distributed CEF)) for making forwarding decisions in the "fast" interrupt path, rather than writing packets into an input queue to be serviced the "traditional" process switched way by a seperate "IP Input" process.
It gets more complicated than that, but thats the general gist of things.
Please rate if this helped,

Hi,
You can go to the "Cisco Feature Navigator", and search by platform "3620":

You get IOS from Cisco web site. The link that Mohammed provides is a good way to get there. Or from the main home page you can login, and under the support tab there is a link for download software.
Note that to download software you must be a registered user on the Cisco site and your profile must have software download privileges (usually dependent on having equipment with a maintenance agreement with Cisco).
