Simulator Upgrades

Architecture

SWIFT IOS is based around the concept of Contained Process Emulation, there are good reasons for this. CPE works by having a native wrapper process which loads UNOS (COFF or .REL) executables, and runs them via a MC68000 emulator. The CPE translates UNOS syscalls into native calls, maps filenames, provides emulated RMB hardware, device support via /dev, and graphics capability via an X display.

The SWIFT Instructor Station upgrade is a complete replacement for Instructor Stations using Charles River Data Systems computers and the UNOS operating system.

SWIFT uses COTS Intel Architecture PC using Linux (OpenSUSE 11). All of the components of the IOS are run as native tasks within which a UNOS environment which is emulated along with a MC68000. The graphics hardware is emulated at the VME ShortIO level and drives standard X11 displays.
