MOUNTAIN VIEW, Calif., April 18, 2013 /PRNewswire/ -- CEVA, Inc. (NASDAQ:
CEVA), the leading licensor of silicon intellectual property (SIP) platform
solutions and DSP cores, today introduced a new low-energy software framework
for Android based systems, which efficiently reduces the power consumption
required for complex multimedia processing using a heterogeneous CPU and DSP
system architecture. Known as Android Multimedia Framework (AMF™), the
framework addresses the most intensive, real-time signal processing
applications, including audio, voice, imaging and vision, and seamlessly
offloads the related tasks from the CPU to the CEVA DSPs at the Android
Operation System (OS) level. Previously, the DSP was detached from the Android
OS, requiring system programmers to implement multimedia tasks and
partitioning at the CPU level, resulting in inefficient use of the CPU to
perform complex, power hungry DSP tasks.

Eran Briman, vice president of marketing at CEVA, commented: "This
comprehensive software framework bridging our application-specific DSPs to the
Android OS is an important milestone for our customers utilizing CEVA's DSPs
and multimedia platforms. AMF was developed in close collaboration with the
CEVA ecosystem of software, system and silicon vendors, contributing their
vast expertise to the design process. The benefits of enabling Android
developers direct access to the processing capabilities of our DSPs are huge,
delivering significant power savings for signal processing-intensive tasks and
enabling the development of a whole new generation of applications for audio,
voice, imaging and vision, which were not practical to implement on CPU
centric architectures."

Android developers can leverage the superior low energy nature of CEVA's
industry-leading DSPs through the AMF to realize significant power savings
when integrating high performance multimedia functionality into their
applications. For example, always-on applications such as face recognition and
voice trigger, including mandatory multi-microphone noise suppression, can be
completely offloaded from the CPU onto a low power CEVA DSP through the AMF,
allowing the CPU to be completely shut down and resulting in approximately 10x
power saving for these applications.

Utilizing AMF, the Android OS supports CEVA DSPs in various system
configurations, including on-chip offloading for Application Processors, as
well as off-chip offloading for companion chips and stand-alone DSP chips.
These include audio CODEC chips incorporating a DSP and image sensors
coprocessors incorporating a DSP. Using standard OpenMAX API, AMF complies
with the current Android 4.x versions. Other benefits/functions enabled by AMF
include:

  oMultimedia tasks are abstracted from the CPU and are physically running on
    the DSP. Furthermore, tasks can be combined ("tunneled") onto the DSP -
    saving data transfer, memory bandwidth and cycles overhead on the CPU
  oScalability – developers can utilize multiple DSPs in the system through
    AMF, e.g. multiple CEVA-TeakLite-4 DSPs, or CEVA-TeakLite-4 for
    audio/voice and CEVA-MM3101 for imaging/vision tasks
  oUtilization of the PSU (Power Scaling Unit) available for CEVA DSPs to
    significantly lower power consumption further, when running multimedia
    tasks
  oEasy activation of CEVA-CV computer vision (CV) software library for the
    development of vision-enabled applications targeting mobile, home, PC and
    automotive
  oSupport for future standards such as OpenVX, a hardware acceleration API
    for computer vision
  oAutomatic tile management for multimedia tasks which includes managing
    memory transfers and organization into DSP memory for efficient processing
  oAn optional Real-Time Operating System (RTOS) is offered for the DSP

The CEVA AMF layers include code and drivers both on the CPU side as well as
the DSP side, including inter-processor communication modules between the
cores and smart scheduling for offloading tasks from the CPU to the DSP.

Bill Teasley, VP Engineering at Sensory commented: "Always-on signal
processing applications such as voice activation and speaker verification
require the lowest possible power consumption, and the CEVA-TeakLite-4 DSP has
proven to offer a very compelling low power profile for our voice activation
solution. Enabling direct access to the CEVA DSPs in Android system
architectures through AMF promises such power-sensitive applications will
reside on the DSP, resulting in more power efficient devices, and envisions
seamless enhancement with new voice recognition components."

Gideon Shmuel, CEO, eyeSight commented: "With the introduction of the new AMF,
the Android ecosystem will be able to develop a new generation of low power
gesture and computer vision applications that can leverage on the processing
capabilities that the CEVA-MM3101 platform offers. AMF will enable Android
developers to overcome these issues by seamlessly offloading imaging and
vision related tasks directly to the CEVA-MM3101, dramatically improving the
performance and battery life for these exciting applications."

Vlatko Milosevski, Business Development Manager at NXP Software said: "The new
AMF will greatly enhance the capabilities that CEVA DSPs can bring to
Android-based systems. Efficiently addressing the low-latency HD voice quality
of LTE smartphones requires more real-time DSP capabilities than ever before.
With CEVA's new AMF offering, Android system developers can harness the full
power of our LifeVibes VoiceExperience software running on the CEVA DSPs
directly, without having to tackle signal processing tasks on the CPU."

AMF is available for the CEVA-TeakLite-4 audio/voice DSP, the CEVA-MM3101
imaging and vision platformand the CEVA-X general purpose DSP.
