AMD-K6™-2E Processor Data Sheet
1.1
The AMD-K6-2E processor with 3DNow!™ technology is a functionally compatible
embedded version of the sixth generation, Microsoft® Windows® compatible
AMD-K6-2 processor. The AMD-K6-2E embedded processor delivers the same high
performance and incorporates the same leading-edge features, including the
innovative and efficient RISC86® microarchitecture, a large 64-Kbyte level-one cache
(32-Kbyte dual-ported data cache, 32-Kbyte instruction cache with predecode data),
and a powerful IEEE 754-compatible and 854-compatible floating-point execution
unit.
The AMD-K6-2E embedded processor also supports the new features incorporated
into the AMD-K6-2 processor. These features include superscalar MMX™ instruction
execution support, support for the Super7™ 100-MHz frontside bus, and AMD’s
innovative 3DNow!™ technology for high-performance multimedia and 3D graphics
operation based on high-performance single instruction multiple data (SIMD)
execution resources.
The AMD-K6-2E embedded processor includes several key features that are very
beneficial to the embedded market. The AMD-K6-2E processor offers leading-edge
performance for embedded systems requiring compatibility with the extensive
installed base of x86 software. The AMD-K6-2E processor’s Socket 7 and Super7
platform-compatible, 321-pin ceramic pin grid array (CPGA) package allows the
product designer to reduce time-to-market by leveraging today’s cost-effective
industry-standard infrastructure to deliver a superior-performing embedded solution.
The AMD-K6-2E embedded processor is available in two versions.
System Management Mode and Power Management Features
The AMD-K6-2E processor includes the complete industry-standard system
management mode (SMM), which is critical to system resource and power
management. (See “System Management Mode (SMM)” on page 217 for more
detailed information about this feature.)
The AMD-K6-2E processor also features the industry-standard Stop-Clock (STPCLK#)
control circuitry and the Halt instruction, both required for implementing the ACPI
power management specification. (“Clock Control” on page 247 provides more
information on these power management features.)

The low-power version has a 1.9-V core voltage and extended temperature rating.
The standard-power version has a 2.2-V core voltage and is the embedded
equivalent of the industry-standard desktop version of the AMD-K6-2 processor.
