In computing, Aemulor is a emulator of the earlier 26-bit addressing-mode ARM microprocessors which runs on ARM processors under 32-bit addressing-mode versions of RISC OS. It was written by Adrian Lees and released in 2003. An enhanced version is available under the name Aemulor Pro.

The software allows Raspberry Pi,[2] Iyonix PC and A9home computers running RISC OS to make use of some software written for older hardware. As of 2012, compatibility with the BeagleBoard single-board computer was under development.

Development

The software's existence was first reported around the time of the announcement of the Iyonix in October 2002.[3][4] A demo version was released in February 2003,[5][6] with the commercial release in March of that year.[7][8][9]

Aemulor Pro was released in 2004. This added enhancements, including support for low colour modes, required by scorewriter Sibelius and many games.[10][11][12] A version for the A9home was released in 2005.[13] The software was exhibited at the 2006 Wakefield Show.[14]

In 2009, author Adrian Lees[15][16] posted on The Icon Bar, showing an early prototype of the software running on the BeagleBoard.[16][17] Progress on further compatibility for the Raspberry Pi single-board computer was announced by Lees on the RISC OS Open forum in 2012.[18] Developer R-Comp was reported in May 2012 to be hoping to make Aemulor available for its BeagleBoard-xM-based ARMini computer.[19]

The software provides full 26-bit emulation[7] for applications written in C and ARM assembly language. It employs an XScale-optimised ARM code interpreter, supports SWI emulation from RISC OS 4 to 5, flag preservation and creation of dynamic areas in low memory.[20] Support for running A310Emu is included, allowing users to further emulate earlier versions of the OS, going back to Arthur.[21] As of 2003, due to the memory remapping employed, native 32-bit applications are restricted to a maximum size of 28Mb while Aemulor is running.[22]

The original release included an Easter egg, with a prize of an upgrade to the Pro version for the person who found it.[23][24]

Aemulor Pro adds support for low-bpp screen modes, sound, hardware emulation of VIDC/IOC, an altered memory map and 26-bit filing systems.[20] Some software, such as Sibelius, can be run both in the desktop and in full screen.[10]
