Athlon MP 1200 (OPN AHX1200ANS3B) based on the Palomino core was a 32-bit x86 multiprocessor developed by AMD and introduced in 2001 for the server and workstation market. This particular model, which operated at 1.2 GHz, had a lower FSB operating at 100 MHz (for an effective transfer rate of 200 MT/s) and operated at higher nominal voltage of 1.8 V. This processor, which was based on the K7 microarchitecture, was manufactured on a mature 180 nm copper interconnect technology at AMD's Fab 30 in Dresden, Germany.

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
