AMD has released two slides which details its next generation HD 79** series GPU architecture. The slides were revealed at the AMD's Fusion developer summit where AMD also officially announced theavailabilityof its Mainstream desktop lineup of Llano APU's.

Looks like AMD would be ditching the VLIW instruction format and looking forward to move towards the SIMD wide-vector execution. You can check out the brief overview of the Slides along with the screenshots below:

Overview

* Ditch the VLIW instruction format and move to SIMD wide-vector execution

* L1 and L2 read / write caching

* Out of order resource allocation

* ECC data protection on SRAMs and global memory

* Parallel primitive

A few highlights from the talk: Multiple primitive pipelines for setup, etc.

Real caching in L1, L2, separate color / z caches for graphics and atomics

Concurrent tasks

Out of order resource allocation

ECC on srams and drams

Shaders

No VLIW, just multiple issue SIMD

Branch, scalar, vector, vector memory, export units

4x16 wide vector ALUs
