23542A/0-September 2000 Preliminary Information AMD-K6™-2E+ Embedded Processor Data Sheet 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 is an extension to the popular and robust Socket 7 platform. See "Super7™ Platform" on page 8 for more information. AMD is the world's second-leading supplier of PC processors compatible with the Windows operating system, having shipped more than 120 million x86 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 splitplane 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.
