K6-2E+/450ACR was a 32-bit x86 embedded microprocessor designed by AMD and introduced in late 2000. Based on the K6-III microarchitecture manufactured on a 0.18 µm process, this model operated at 450 MHz with a TDP of 17.5 W.

Cache

Main article: K6-III § Cache

[Edit/Modify Cache Info]

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.
