IA-32 Execution Layer

A software-based x86 translation layer for the Itanium family of CPUs. IA-32 Execution Layer (IA-32 EL) ships with Itanium-based operating systems and is used to translate x86 instructions into native Itanium instructions for execution. IA-32 EL provides a way to run legacy applications "as is" before they can be recompiled into native Itanium programs. See Itanium.

Chip maker Intel Corp has released its IA-32 Execution Layer software for use in systems featuring the Intel Itanium 2 processor and a Microsoft Windows operating system.
This is achieved by integrating the IA-32 Execution Layer software into the operating system so that support for IA-32 applications is carried out at the software level, translating IA-32 application code into native Intel Itanium architecture code.
In this vein, at press time Intel had just announced that the company is working with Microsoft to help Redmond create a 32-bit emulation layer for Itanium, called the IA-32 Execution Layer, in Windows.
