GENERAL DESCRIPTION

Table 1. Clocking Options

Operating

TheAm5_X86™microprocessorisan 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_X86 microprocessor family.

The Am5_X86 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
