POWERVR MBX IP Core Family
POWERVR MBX IP Core Family
Imagination Technologies’ POWERVR™ MBX Graphics Processing Unit (GPU) IP family of 2D/3D accelerators has
been successfully deployed in a wide range of markets including mobile phone, personal navigation, consumer
STB devices, in-car information and amusement systems.
The underlying POWERVR MBX architecture is fully
scalable for a range of area and performance
requirements, enabling it to accommodate the needs of
many target markets.
POWERVR's unique tile-based rendering architecture
enables higher performance and higher image quality
at lower power consumption and silicon area than
competing technologies.

Advanced full-scene anti-aliasing
Unique patent protected tiling technology enables
on-chip processing of hidden surface removal (pixel
perfect and submission order independent) and pixel
blending, and enables deferred rendering, eliminating
all unnecessary access to off-chip memory. The
decoupling of geometry and vertex processing from the
rasterisation process enables higher throughput while
maximizing tolerance to system latencies. Advanced
tiling and culling algorithms are implemented in
hardware, which in combination with seamless scene
complexity management and compression enable
support for arbitrarily complex scenes in limited
memory footprints with lowest memory bandwidth
usage.

POWERVR Vertex Geometry Processor
POWERVR Internal True Colour
The POWERVR Vertex Geometry Processor (VGP) is a
high-performance, fully programmable floating-point
SIMD coprocessor carefully matched to the
requirements of 3D. Designed for optimal geometry
processing (including transformation and lighting), the
VGP offloads these highly compute-intensive tasks
from the host CPU resulting in a significant reduction
in power consumption. With an instruction set
carefully designed to allow common geometry
operations to be performed in a minimal number of
instructions, the VGP is capable of four floating-point
operations per clock.
Colour operations are always performed on-chip at
32-bpp irrespective of frame buffer bit depth for
superior colour precision at zero cost.
Wide industry-standard API and OS support
All POWERVR MBX cores share a rich feature set that
enables support for all major industry Application
Programming Interfaces (API) across a wide variety of
Operating Systems (OS).

OS support
Linux, Symbian OS™, WinCE (additional OS
support through POWERVR Insider Ecosystem)
POWERVR Texture Compression (PVRTC)
Imagination’s unique patented royalty-free texture
compression algorithm allows texture data to be
stored with only 2 or 4 bits per pixel for small memory
footprints and application distribution size.
Advanced full-scene anti-aliasing (FSAA)
The POWERVR architecture includes extensive support
for a wide range of anti-aliasing options with minimal
bandwidth cost and zero memory footprint overhead,
including multi-sampling and super-sampling options
up to 4x and beyond. A unique algorithm allows an
extended set of processing options under OpenVG
enabling up to 16x FSAA.
Low power
POWERVR MBX cores are built on a foundation of
unique patent-protected technologies that deliver
class-leading performance while keeping power
dissipation to a minimum. In addition, sophisticated
clock gating power management techniques ensure
the lowest active and standby power consumption.
Performance
Applications
POWERVR MBX family currently comprises two
variants scalable for a range of area and performance
requirements enabling it to accommodate the needs
for many target markets. Performance scales with
clock speeds up to 233MHz and beyond.
