The CS49400 DSP integrates a multi-channel audio decoder and a
32-bit audio processor with an audio optimized software
framework—it’s the ideal, economical solution for AV receivers.
Feature rich AVR designs can be easily developed using this
framework, which includes both certified application programs and
a modular programming envionment for easy customization. The
framework includes state-of-the-art audio decoders and audio
enhancement programs, such as DTS-ES 96/24, Dolby Digital, AAC,
and THX. Framework API along with a comprehensive suite of
development tools is available for manufacturers to incorporate
unique sound processing.
The CS49400 DSP was designed to reduce system costs while
providing features and flexibility for competitive system level
solutions. It provides system level peripherals and internal
memory—helping to drive down system costs. Difficult processing
tasks of AAC, DTS-ES 96/24, and THX Cinema can be accomplished
without the expense of external logic or memory. This DSP can meet
the needs of I/O intensive designs supporting up to 12 input
channels and 16 output channels. The CS49400 is an economical
solution for a variety of applications including AV receivers, outboard
decoders, DVD receivers, and DVD Audio/Video/SACD players.
