Imagination delivers latest HD video encoder IP core with full H.264 High Profile capability

POWERVR VXE380 delivers the highest quality multi-standard HD encode of any synthesisable IP core


Yokohama, Japan: Imagination Technologies, the leading multimedia chip technologies
company, announces POWERVR VXE380, the latest member of Imaginations
third generation video encoder IP family, which delivers multi-standard encoding
of video, now including H.264 High Profile (HP), at HD resolutions.

The newest
member of the POWERVR VXE encoder family delivers the highest quality encode
ever seen in a synthesisable IP core, and offers the most complete
implementation of the High and Main Profile toolsets of any IP core available
in the market today.  This
translates to improved image quality at all bit rates, and enables ultra-low
bitrates to be achieved for encoded streams with minimum degradation from the
original source image data.

Says Tony
King-Smith, VP marketing, Imagination: “”With the relentless growth in demand
for high quality user-generated content in all forms of mobile devices, we’ve
seen tremendous interest in our VXE HD video encoder products. Our partners
have evaluated our advanced encoding algorithms used in VXE380 against many
other solutions, and the feedback we’re getting indicates we have a winning
solution that is the ideal complement to the growing numbers of HD resolution
image sensors now being deployed in mobile devices.””

Imagination will
be delivering a paper on POWERVR VXE technology at Embedded Technology in
Yokohama from 18-20th November 2009.

POWERVR VXE
encodes video sequences and still images to a wide range of compression
standards including H.264 High, Main and Baseline Profiles, H.263, MPEG-4,
M-JPEG and JPEG. These cores offload the entire video/still encode processing
to hardware, minimising host CPU processing load, enabling lowest power
solutions without compromising performance. The core is fully supported by an
accompanying software stack, which includes an OpenMAX IL compliant API under
Linux.

The core is
scalable, allowing Full HD video to be encoded, as well as offering the ability
to record at extremely high frame rates (e.g. >1200 fps at QVGA) for
detailed slow motion capture – one of the most sought after features for
encoders today.  Support for 4K
resolutions is also possible, due to Imagination’s unique scalable
architecture.

The third
generation, intelligent motion search algorithm dramatically reduces memory
bandwidth requirements, whilst offering an even larger effective search range
to give the best possible video quality and compression ratios. As memory
access is one of the key sources of high power consumption for a SoC
(System-on-Chip), this reduction in bandwidth also helps lower the overall SoC
power requirements.

The IP core contains a small embedded 32-bit
META processor, which ensures that the rate control algorithms are both
flexible and highly capable, without burden or reliance on the host
processor.  This flexibility gives designers
the ability to meet specific rate control requirements for the most demanding
applications.

The VXE380 IP
core, like all of Imagination’s IP cores, is designed with ease of system
integration in mind, requiring minimal external components, supporting memory
interfaces optimised for all popular DRAMs including the latest DDR3 devices.

The POWERVR VXE
family of encoders is ideal for a wide range of consumer and embedded
applications including mobile phones, digital cameras, Blu-Ray disc authoring,
portable media players, video conferencing, surveillance, personal navigation
devices, personal video recorders and hardware encode accelerators.

The POWERVR
VXE380 IP core is available for licensing now.
