Larrabee's Rasterisation Focus Confirmed

[3dilettante]

Intel never gave an estimate of anything beyond the core size. In my interpretation, it never included anything but the execution core + L1s in the 10mm2 estimate.

Without knowing the number of other units and their relative areas, I couldn't estimate more than 32 times the estimated core area. Obviously, the non-core elements have an area >>0.

This is bloody tantalising:

But it's hidden and I can't find anything else on the topic :sad:

How is it hidden? It just appears to describe using polynomial evaluation with a small number of different polynomials for each function on a particular hardware architecture.

Plebs like me can't read the document: pay to view.

With this and the Imagine paper kindly forwarded to me, hopefully there's some clues on what Intel will be doing for transcendentals on Larrabee.

Presumably there'll be a split between single-precision high-speed versions for graphics and something more refined for double precision.

I'll look at these later. Thanks all.
