AMD-K6-2E+ Embedded Processor Data Sheet
Preliminary Information
In addition, the processor supports advanced branch prediction logic by
implementing an 8192-entry branch history table, a branch target cache, and a return
address stack, which combine to deliver better than a 95% prediction rate. These
design techniques enable the AMD-K6-2E+ processor to issue, execute, and retire
multiple x86 instructions per clock, resulting in excellent scaleable performance.
Industry-Standard x86 Architecture
The AMD-K6-2E+ processor is x86 binary code compatible. AMD’s extensive
experience through six generations of x86 processors has been carefully integrated
into the processor to enable compatibility with Windows 98, Windows 95, Windows
3.x, Windows NT, DOS, Linux, OS/2, Unix, Solaris, NetWare, and other leading x86
operating systems and applications. The AMD-K6-2E+ processor is also compatible
with leading real-time operating systems (RTOS) commonly used in embedded
applications, such as pSOS, QNX, RTXC, and VxWorks. Additionally, the AMD
FusionE86SM third-party tool support program offers extensive development support
for AMD-K6-2E+ processor designs.
The AMD-K6-2E+ processor is Super7 and Socket 7-compatible. The Super7 platform
AMD is the world’s second-leading supplier of PC processors compatible with the
Wi ndows ope rating sy stem, hav i ng shipped more than 12 0 m illi on x 8 6
microprocessors, including more than 60 million Windows-compatible processors. The
AMD-K6-2E+ processor for embedded applications is the latest member in this long
line of processors. With its combination of state-of-the-art features, industry-leading
performance, high-performance 3DNow! technology and multimedia engines, x86
compatibility, and low-cost infrastructure, the AMD-K6-2E+ processor is the superior
choice for high-performance embedded systems.
1.2
Process Technology
The AMD-K6-2E+ processor is implemented using an AMD-developed, state-of-the-art
low power 0.18-micron process technology. This process technology features a split-
plane design that enables the AMD-K6-2E+ processor to deliver excellent
performance solutions while utilizing a lower processor core voltage, which results in
lower power consumption, while the I/O portion operates at the industry-standard
3.3-V level.
