Why is Level 1 cache located on the RAM

[Ali Inam]

Why is Level 1 cache located on the RAM while the others are located between the RAM and the microprocessor ? !

 

[rcgldr]

Level 1 cache is normally closest to the cpu. Page tables for virtual to physical address translation are in ram, but a translastion lookaside buffer cache is used to speed that process up.
