Omega XScale support in 2004?By Chris Williams. Published: 20th May 2004, 22:34:12 | Permalink | Printable
Didn't we ask this last year?In the latest newsletter from Desk, published yesterday, the Dutch dealer has reported that Microdigital are currently focused on completing their 'ARMTwister' technology for the StrongARM powered Omega computer. Desk have suggested that Microdigital are aiming to have demonstrable, working XScale support ready in time for the Expo show.
Desk are also the main sponsors of this year's Expo event, which is to be held next month in the Netherlands.
The Omega currently runs RISC OS 4, which is a 26bit OS, whereas the Intel XScale processor that MD want to use is fully 32bit and has no 26bit support. According to Microdigital, the ARMTwister is "a JIT (just-in-time) code translation system to convert 26bit-only instructions into the 32bit equivalent ones, on the fly. It is implemented in the Omega NorthBridge FPGA. This takes advantage of the natural parallelism of hardware to implement the various table look-ups and calculations necessary to convert ARM code, as it is loaded into the CPU instruction cache."
The Omega was first announced in October 2000, and eventually shipped in 2003.

Moving tributes to Paul Vigay flood in
Hundreds of heartfelt tributes have been paid to popular RISC OS advocate and ISP owner Paul Vigay, who was found dead off the south coast on Friday morning. Close friends described civil liberties campaigner Paul, 44, as "kind, sincere and patient" and "an extremely clever deep-thinker".
