Tokyo, Japan:
Technologies, the leading multimedia chip technologies company,
will begin shipping fully verified production
quality IP for its POWERVR SGX543MP multiprocessor graphics cores to partners
before the end of December 2009. Multiple lead partners have already been
working with beta versions of the core for several months and several SoCs for
a range of markets incorporating SGX MP cores are already in advanced design.

Imagination reports that three of its
partners now have licences for SGX MP technology, which continues to extend
Imagination’s leadership of the embedded graphics acceleration market with multi-processor,
shader-based solutions which address the rapidly growing demands for high
performance graphics in a wide range of consumer electronics segments.

The technology can be delivered to customers in SGXMP2 (two-core) to
SGXMP16 (16-core) variants.Graphics IP
cores available from Imagination now range from SGX520, the world’s smallest
OpenGL™ ES 2.0 mobile core, to SGX543MP solutions for high-performance console
and computing devices. POWERVR SGX543MP delivers performance comparable to many
desktops, laptops and games consoles.

Further details of the innovative technology
behind POWERVR SGX543MP are being revealed to press and customers at the
Embedded Technology Show in Yokohama, Japan from 18-20th November

Tony King-Smith, VP marketing Imagination
Technologies says: “”With the ability to combine up to sixteen SGX543MP GP-GPU
cores on a single SoC, we are now able to deliver capabilities to our
licensing  partners previously only
thought the domain of the discrete GPU chipset vendors, while maintaining our
unrivalled power, area and bandwidth efficiency.””

The POWERVR SGX543MP family enables POWERVR
SGX543 four-pipe programmable GP-GPU cores, to be integrated in a high
performance, multi-processor graphics solution without performance or silicon
area compromises. SGX543MP enables highly linear scaling of all aspects of
GPU performance, specifically vertex shading, pixel shading, primitive setup
and overall GP-GPU* functionality, whilst maintaining full software
compatibility and with virtually no overhead in bandwidth usage.

At 200MHz core frequency an SGX543MP4 (four
cores) will deliver 133 million polygons per second*** and fill rates in excess
of 4Gpixels/sec**. Higher frequencies or a larger number of cores each deliver
more performance. At 400MHz core frequency an SGX543MP8 (eight cores) will
deliver 532 million polygons per second*** and fill rates in excess of 16Gpixels/sec**.

The highly efficient POWERVR SGX543MP family
delivers near linear progression in vertex and pixel processing performance,
unlike competitive solutions which scale only pixel performance. An SGX543MP2
delivers effectively twice the performance of a single SGX543 without
compromise. And for a given workload the same bandwidth is required no matter
how many cores are deployed – SGX543MP delivers faster performance by dividing
the work on-demand, dynamically load balanced in parallel between cores.

The USSE2 (Universal Scalable Shader Engine
v2), a key component of Series5XT architecture at the heart of SGX543MP is a
scalable multi-threaded multimedia processing engine offering up to 2x the floating
point throughput of earlier Series5 SGX IP cores. An extended instruction set
with comprehensive vector operations and co-issue capabilities enables advanced
geometry and pixel processing as well as GP-GPU tasks. These tasks are broken
down into processing packets which are then scheduled across a number of
multi-threaded execution units in the USSE2. This enables optimal hardware load
balancing, maximum latency tolerance and efficient gate use, all accessed
through a single software programming model and compiler.

POWERVR SGX543MP features:

  • the highest
    performance per mW of any embedded graphics core
  • highly linear scaling (over 95% efficiency) of performance in both
    geometry (vertex processing) and rasterisation (pixel/fragment processing)
  • dynamic load balancing and on-demand task allocation at the
    pipeline level
  • no fixed allocation of given pixels to specific cores, enabling maximum
    processing power to be allocated to the areas of highest on-screen action
  • scalable GP-GPU compute power, which can be fully utilised through
    all Khronos APIs including OpenGL ES 2.0/1.1, OpenVG™ 1.x and OpenCL™
  • use any number of cores, even or odd
  • no additional work for software developers; using one driver stack
    for all SGX cores means applications see a common SGX architecture via the
    standard APIs regardless of number of cores used
  • no additional CPU load when using multiple cores or loss of performance
  • individual cores can be disabled based on workload for optimal
    power saving
