INTRODUCTION

The embedded Write-Back Enhanced IntelDX4™ processor provides high performance to 32-bit, embedded applications. Designed for applications that need a floating-point unit, the processor is ideal for embedded designs running DOS*, Microsoft Windows*, OS/2*, or UNIX* applications written for the Intel architecture. Projects can be completed quickly using the wide range of software tools, utilities, assemblers and compilers that are available for desktop computer systems. Also, developers can find advantages in using existing chipsets and peripheral components in their embedded designs.
