The market for digital high definition audio (HD audio) solutions
including Blu-ray Disc players, Digital TVs, Set-top boxes and home
entertainment systems is dynamic and highly competitive. Digital
HD audio devices are dramatically increasing in popularity, and
there is a strong demand for lower cost and higher performance equipment.
The latest HD audio devices require sophisticated use-cases, including
support for 2 HD audio decoders (supporting 7.1 and 5.1 channels),
a 5.1 channel audio encoder and advanced post-processing functions.
These market requirements translate into demand for integrated optimized
platforms consuming smaller die size without compromising on audio
performance.
To meet these challenges, CEVA has developed CEVA-HD-Audio™,
a DSP-based single-core audio platform targeting high-volume ICs
for devices such as Blu-ray Disc players, DTVs and home entertainment
systems.
CEVA-HD-Audio is a high-performance, low-cost platform that combines
several CEVA-developed technologies including the CEVA-TeakLite-III™
DSP core, a configurable cached audio subsystem, a comprehensive
set of optimized HD audio codecs, and complete software development
kit, including software development tools, prototype boards, systems
drivers and RTOS. This complete solution, fully developed and maintained
by CEVA, ensures quick and easy development and integration into
the customer's SoC.
CEVA-HD-Audio is further enhanced by the vast CEVAnet
partner program, whereby partners provide additional audio elements
to enhance the CEVA-HD-Audio based products.

The CEVA-HD-Audio solution is
comprised of four key elements:
| |
|
 |
Programmable DSP Engine - a 550MHz
CEVA-TeakLite-III
is a high performance, yet small die size and low-power DSP
core, optimized for audio processing |
|
Configurable Memory Subsystem - the
CEVA-TL3210, a highly integrated, compact DSP subsystem, incorporating
a CEVA-TeakLite-III core, a configurable cached memory architecture
with a small memory footprint, an optional DMA engine for efficient
data transfers, and an AMBA standard bridges for easy system
integration |
|
Audio Software - CEVA's open, programmable
platform contains a comprehensive set of industry standard audio,
speech and voice codecs, optimized for the CEVA-TeakLite-III
DSP, taking into consideration typical audio system limitations |
|
Complete Software Development Kit (SDK)
- a complete software development suite, including development
tools, development boards, software system drivers and RTOS,
for easy application development and system integration from
initial design through final tape-out |
