I heard it can be done (clearing out CPU cache).  Like memdump or something.  How does one zero out the cpu's cache L1, 2 and 3?  It's static memory (SRAM) to be cleared.  Thanks

Why do you need to do so? Anyhow, if you want to clear the data cache, just write a program with a large enough array full of zeroes and loop over it without any optimizations.
