The AMD Athlon™ processor is the first member of a new
family of seventh-generation AMD processors designed to meet
the computation-intensive requirements of cutting-edge
software applications running on high-performance desktop
systems, workstations, and servers. This technical brief
describes the features of the AMD Athlon processor’s
microarchitecture.
The AMD Athlon processor’s microarchitecture is designed to
support the growing processor and system bandwidth
requirements of emerging software, graphics, I/O, and memory
technologies. The AMD Athlon processor's high-speed
execution core includes multiple x86 instruction decoders, a
dual-ported 128-Kbyte split level-one (L1) cache, three
independent integer pipelines, three address calculation
pipelines, and the x86 industry's first superscalar, fully
pipelined, out-of-order, three-way floating-point engine. The
floating-point engine is capable of delivering 2.4 gigaflops
(Gflops) of single-precision and more than 1 Gflop of
