Trident Microsystems Inc. has announced that is has produced a set-top
box platform based on an ARM A-series processor. In a separate
announcement Ittiam Systems Private Ltd. said it has implementated a
Dolby MS10 multistream audio decoder on the A series of processors.
Trident's work on a set-top box has produced a design that can handle
both broadcast and internet traffic using a Cortex-A series processor.
(Sunnyvale, Calif.) took over the digital television and set-top box IC
endeavors of NXP Semiconductor BV (Eindhoven, The Netherlands) in a deal
in 2009. Trident has designed a 45-nm integrated SoC based on the
Cortex-A9 processor that is able to handle streaming broadband and
is working with ARM & Trident to optimize the ARM JIT performance
for ActionScript 3.0 which is used in the Flash Platform and provides
the fundamental engine for driving our runtimes in digital home
devices," said Jennifer Carr, senior director, business Development at
Adobe. HTML5, which incorporates features like video playback, has been
optimized for ARM.
Ittiam's audio platform includes Dolby Digital Plus (DD+), Dolby Digital
(DD), Dolby Pulse decoder and Dolby Digital Encoder in a single package
for next generation digital televisions (DTV) and set-top-boxes (STB).
bandwidth required for the decoding of a Dolby Digital stream at 48-kHz
in 5.1 multi-channel mode is 22 million cycles per second (MCPS) on the
Cortex-A9 processor, ARM said. The bandwidth requirement for HE-AAC v2
(5.1) and DD+ decoders is lower than 50 MCPS each. For encoding, the
average performance bandwidth required for the DD 5.1 encoder is less
than 70 MCPS, so it is possible to perform both decode and encode at the
same time on a Cortex-A9 processor.
utilizing the Neon engine, our MS10 implementation takes up less than 10
percent of the processor load while offering cost and time benefit in
the integration of advanced audio technologies," said Shantanu Jha, vice
president, media processing at Ittiam, in a statement issued by ARM.
