Imagination Technologies – a leader in silicon IP cores – debuts its PowerVR
SGX Shader Graphics Accelerator family, the future of wireless mobile embedded
graphics and video technology.

The PowerVR SGX cores for wireless applications are part of Imagination’s
PowerVR Series5 scalable and fully programmable unified shader graphics and
video core family, previously codenamed Eurasia. The first cores from this
family target mainstream and performance mobile graphics with state-of-the-art
support for 2D and 3D and an industry leading feature set that exceeds OGL 2.0
shader and Microsoft Vertex and Pixel Shader Model 3 requirements.

PowerVR SGX is available for licensing in three scaled variants (PowerVR SGX510,
SGX520, SGX530) with sizes ranging from less than 2mm2 to 8mm2 in 90nm
technology. These variants will enable a wide range of mobile devices from basic
phones and entry-level feature phones to mainstream feature phones and advanced
feature and smart phones.

“Despite its very small size PowerVR SGX will set a tough benchmark that any
competitors will have to stretch to compare with and, with advanced
programmability and state-of-the-art shader features, will enable content
developers to create a distinct new generation of mobile games and
applications,” says Hossein Yassaie, CEO, Imagination Technologies.

PowerVR SGX enables the highest performance, most efficient and lowest power
consumption solution for handheld 3D graphics and video. Each scalable PowerVR
SGX variant provides highly flexible support for video codecs with zero silicon
overhead, using the advanced programmability of the core.

PowerVR SGX builds on the architectural benefits found in Imagination’s PowerVR
MBX family, which is already the de facto standard for mobile graphics with
licensees including six of the world’s top 10 semiconductor manufacturers. The
first PowerVR SGX deliverables will be available for shipping to lead partners
from next quarter.

The PowerVR SGX family will co-exist alongside PowerVR MBX, which is currently
integrated in a variety of devices including mobile handhelds, car navigation
and entertainment systems.

PowerVR SGX510, SGX520 and SGX530 are compatible with content created for
PowerVR MBX. PowerVR SGX is backwardly compatible with key features from the
PowerVR MBX family like the vertex shader programs and 2 and 4-bit PVR-TC™
texture compression. These compatibilities, and continued support for all
existing PowerVR extensions to OpenGL ES 1.1, allow comprehensive software
support developed on the PowerVR MBX platform to be carried forward to PowerVR
SGX.

The PowerVR SGX Difference
The new-generation PowerVR SGX offers all the advantages of PowerVR’s highly
efficient tile based architecture. Unlike traditional graphics solutions that
demand expensive memory or very large silicon areas, PowerVR’s unique, patented
tile-based rendering and deferred pixel shading architecture allows a very small
silicon die to deliver higher performance and higher image quality, at lower
power consumption, than competing technologies.

PowerVR SGX takes the PowerVR architecture to the next level with a unified
scalable shader engine (USSE™), which combines vertex shader and pixel shader
features in a single scalable processing unit, enabling mobile semiconductor and
device manufacturers to plan a roadmap where PowerVR will continue to enable the
best performance in the most efficient architecture for the mobile industry.

Shader technology enables superior realism and advanced features when rendering
3D objects and, by making 3D effects more programmable, gives freedom to content
developers to create more visually compelling and unique games and applications.

Continues Yassaie: “With its PowerVR deferred pixel shading architecture the
PowerVR SGX family has the lowest core and system power demands. It’s ideal for
unified memory systems plus integrated CPU designs in mobile and cost sensitive
applications. Couple that with wide standards compatibility, high scalability
from a unified shader architecture, pipeline scalability from 1x to 8x and
beyond and video encode and decode for free, and you have a solution that is
demonstrably superior to any other offering on the market.

“With PowerVR SGX we expect to maintain our hard-won leadership position on
size, power and performance – and its scalability means it’s suitable for a wide
range of end-user products. The specification says it all: this is the premier
wireless graphics solution and will enable our partners to continue the
reshaping of the mobile multimedia market they have already begun using our
technology.”

Says Dr. Jon Peddie, the leading market researcher in graphics: “The mobile
phone is advancing in functionality at a 3X pace compared to the PC, and future
high-end phones will incorporate the OpenGL ES 2.0 API with shader capabilities,
similar to features found on high-end PCs. Imagination Technologies, with design
wins in most of the major handsets, continues its lead by being the first to
introduce a design with support for this new API and we expect this new
technology to fuel the next wave in modern advanced mobile phones.”

Inside PowerVR SGX
The PowerVR SGX family features the USSE™ unified scalable shader engine, which
combines vertex shader and pixel shader features in a single programmable and
highly scalable processing unit. Maximum gate utilisation is achieved by sharing
the unit for both vertex and pixel processing with optimal automatic load
balancing of vertex and pixel throughput, which are often different from
application to application.

PowerVR SGX’s USSE supports advanced geometry and pixel processing capabilities
such as procedural geometry (e.g. higher order surfaces, data instancing, path
based geometry, point-sprite expansion etc.) and textures, advanced per pixel
and vertex lighting effects (e.g. parallax bump mapping, refraction and
reflection etc). Further, the highly flexible nature of the USSE architecture
allows this programmability to be applied to many other tasks such as other
multimedia related activities (e.g. physical modelling), flexible video and
image processing and many more. This unified approach to processing also has the
benefit of requiring a single unified programming model with one compiler,
reducing hardware and software qualification time.

PowerVR SGX’s latency tolerant architecture provides geometry processing and
rasterisation decoupled to achieve minimal stalling as well as no pixel shading
of non-visible pixels and on-chip support for multiple render targets (MRT). A
large proportion of PowerVR SGX’s peak throughput is achievable in real
applications and the architecture has the lowest bandwidth requirements as
PowerVR SGX’s deferred pixel shading gives 2x – 3x fill rate compared to other
solutions at the same bandwidth. Across the wireless PowerVR SGX family parts
effective fillrate performance is from 200Mpix/sec to 1200Mpix/sec @ 200MHz
(with even higher Z and stencil rates) and polygon throughput is from 2Mpoly/sec
to 13.5Mpoly/sec @ 200Mhz.

Z and Stencil tests are performed on-chip requiring no external stencil or
Z-buffer memory or bandwidth. Pixel shading and blending are also performed
on-chip and compressed texture support is just part of an industry leading
feature set which also supports OpenGL ES 2.0, OGL 2.0 and Microsoft Shader
Model 3.0 capable shaders, procedural geometry and MRTs.

PowerVR SGX enables compelling image quality via Internal True Colour™ -
enabling colour operations to be performed on-chip using high precision
mathematics at arbitrary pixel colour precision up to 128bit/IEEE32 floating
point – combined with comprehensive programmable multi-sampling image
anti-aliasing for free.

A key benefit of PowerVR SGX’s tiling architecture is on-chip multiple render
targets (MRT). This technology is unique to PowerVR tile based rendering and
cannot be replicated by an immediate mode renderer (IMR) in a cost-effective
manner. IMRs use conventional external MRTs with huge external memory storage
and bandwidth. PowerVR’s on-chip MRTs result in low geometry processing with no
additional external memory cost and no additional memory bandwidth cost.

All major 2D operations are accelerated, including: BLTs, Alpha Blend BLTs, ROP
2, 3 & 4s, lines and surface rotation.

PowerVR SGX fully supports the broadest range of mobile standards including
OpenGL ES 2.0, OpenGL ES 1.X, D3D Mobile, OpenVG, JSR184 and JSR239, DX9+ and
Open GL 2.0 APIs running under Linux, Symbian, WinCE and Windows Mobile OS.

Video For Free
Because of PowerVR SGX’s fully programmable architecture it can support video
acceleration for free, without increasing the size and complexity of the core.

Video is a core competence of handheld graphics processors and is increasingly a
must-have feature, not just in Personal Media Player products, but also other
mobile devices. PowerVR SGX provides outstanding image quality and frame rates,
offloading video codec processing (including MPEG-4 and H.264) from the main
CPU. For video operations the host CPU load is minimal and the PowerVR SGX part
can perform motion estimation, motion compensation and transform, residual
generation, transform, quantisation, inverse quantisation, inverse transform,
image reconstruction, and deblocking (H.264), making it possible to efficiently
off load the tasks associated with video compression/decompression from the host
CPU.

As well as enabling the playback of users own personal media content, PowerVR
SGX’s advanced video capabilities will enable mobile services such as
TV/video-on-demand and video messaging. PowerVR SGX also supports still image
standards including JPEG and JPEG2000.
