GENERAL DESCRIPTION
The Am5
X
86 microprocessor is an addition to the AMD
microprocessor product family. The new processor en-
hances system performance by raising the microproces-
sor operating frequency to the highest levels allowed by
current manufacturing technology, while maintaining
complete compatibility with the standard Am486 proces-
sor architecture and Microsoft
Windows
. The CPUs
incorporate write-back cache, flexible clock control, and
enhanced SMM. Table 1 shows available processors
in the Am5
X
86 microprocessor family.
The Am5
X
86 microprocessor family allows write-back
configuration through software and cacheable access
control. On-chip cache lines are configurable as either
write-through or write-back. The CPU clock control fea-
ture permits the CPU clock to be stopped under con-
trolled conditions, allowing reduced power consumption
during system inactivity. The SMM function is implement-
ed with an industry standard two-pin interface.
