getting info on Cache Size, Data Cache etc..

Hi all
I saw in Microsoft web site www.SysInternals.com a tool called CoreInfo from able to print out on screen the size of the Data and Instruction caches of your processor, the Locigal to Physical Processor mapping, the number of the CPU sockets. etc..
Do you know if in Linux is available a command like this?
Thanks for the help

You mean besides the stuff you can get from /proc/cpuinfo and dmesg?

Great! it was what I was looking for!
Thanks!
