Gallery of Processor Cache Effects

There's more to technical brilliance than, well, technical brilliance. Clear exposition helps, and this is the clearest exposition of processor cache operations I've ever read.

Most of my readers will understand that cache is a fast but small type of memory that stores recently accessed memory locations. This description is reasonably accurate, but the "boring" details of how processor caches work can help a lot when trying to understand program performance.

Notes: If you put a <mailto:> link in the URL field your address will not be mangled: this could be a bad idea as your email address could be easily harvested by bots designed for SPAM. The comments field should now format correctly for line feeds and carriage returns: when you hit the 'Enter' or 'Return' keys in your comment it should break to a new line. The text should wrap cleanly. Please let me know if it doesn't. No HTML tags will pass through - entering links seems to be the main cause of comment SPAM. Also, please be sure that Javascript is enabled in your browser before attempting to post a writeback. Sorry for any inconvenience, but this really helps cut down on the amount of comment SPAM I have to deal with.
