primary cache
<hardware, architecture> (L1 cache, level one cache) A small, fast cache 
memory inside or close to the CPU chip.
 
For example, an Intel 80486 has an eight-kilobyte on-chip cache, and most 
Pentiums have a 16-KB on-chip level one cache that consists of an 8-KB 
instruction cache and an 8-KB data cache.
 
The larger, slower secondary cache is normally connected to the CPU via its 
external bus.
