Atom™ Processor E6xx Series Datasheet

— 3D peak performance

— Fill rate: two pixels per clock

— Vertex rate: One triangle 15 clocks (transform only)

— Vertex/Triangle ratio average = 1 vtx/tri, peak 0.5 vtx/tri

• Texture maximum size = 2048 x 2048

• Programmable 4x multi-sampling anti-aliasing (MSAA)

—Rotated grid

— ISP performance related to AA mode, TSP performance unaffected by AA mode

• Optimized memory efficiency using multi-level cache architecture

7.2.2 Shading Engine Key Features

The unified pixel/vertex shader engine supports a broad range of instructions.

• Unified programming model

— Multi-threaded with four concurrently running threads

— Zero-cost swapping in/out of threads

— Cached program execution model – unlimited program size

— Dedicated pixel processing instructions

— Dedicated vertex processing instructions

— 2048 32-bit registers

• SIMD pipeline supporting operations in:

— 32-Bit IEEE Float

— 2-way, 16-bit fixed point

— 4-way, 8-bit integer

— 32-bit, bit-wise (logical only)

• Static and dynamic flow control

— Subroutine calls

—Loops

— Conditional branches

— Zero-cost instruction predication

• Procedural geometry

— Allows generation of more primitives on output compared with input data

— Effective geometry compression

— High order surface support

• External data access

— Permits reads from main memory by cache (can be bypassed)

— Permits writes to main memory

— Data fence facility provided

— Dependent texture reads
