The ARIES emulator
Basics
Aries is the HP-UX PA-RISC to HP-UX IPF binary emulator or dynamic code translator. Aries
transparently emulates both 32-bit and 64-bit HP-UX PA-RISC 2.0 applications on HP-UX IPF,
thus providing binary compatibility for PA-RISC binaries on IPF systems. It is transparent in that
users need not do anything special to simply run their PA programs on IPF.
The HP-UX/IPF kernel (exec(2)) will recognize PA executable files (both 32- and 64-bit fields)
and invoke Aries to emulate these processes. Aries will handle all instruction set architecture
(ISA) emulation and enviournment emulation on behalf of the PA program, and present a virtual
PA machine achitecture to the emulated program.
There are actually two versions of Aries: one for emulating PA-32 processes, and one for PA-64
processes. This is necessary because Aries must keep the address space layout that the emulated
process expects; natively, then Aries-32 is a 32-bit process, and Aries-64 is a 64-bit process.
