Preliminary Information

1.1

AMD-K6™-2E Embedded Processor Features

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.

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.

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.)
