Tensilica Previews Next-Generation Audio Technology
At Spring Processor Forum
Santa Clara, Calif. – May
17, 2005 – Tensilica, Inc., the
only company to automate the design of optimized
application-specific configurable processors
for system-on-chip (SOC) design, will preview
its next-generation audio technology at the Spring
Processor Forum in San Jose, CA, Wednesday afternoon,
May 18, 2005 (see http://www.in-stat.com/spf/05/
for more details). By leveraging Tensilica’s
Xtensa LX configurable processor technology,
Tensilica’s engineers are developing a
turn-key audio solution with lower power, faster
processing, and a full set of optimized audio
encoders and decoders for popular standards such
as AAC, MIDI, MP3, and WMA.
The next-generation audio engine will take advantage
of Tensilica’s Xtensa LX capability to selectively
use specially designed dual-issue 64-bit instructions
to significantly improve performance. Over 300
audio-specific instructions are being added to
Tensilica’s Xtensa LX configurable processor
to optimize it for audio streams. Some of these
instructions include:
* Dual multiply/accumulate, each supporting 24x24
and 32x16 bits
* Huffman encode/decode and bit stream support
* Two special audio register files with multiple data types
* Two-way SIMD arithmetic and Boolean operations
Tensilica’s first-generation audio product,
the Xtensa HiFi Audio Engine, has been designed
into integrated circuit designs for several cellular
phone handsets and other portable consumer devices.
Robert Kennedy, Tensilica’s senior software
engineering manager, will deliver the presentation
at this prestigious conference. Tensilica expects
to make a formal announcement and have this second-generation
audio engine available for customer shipment in
the fall of this year.
