The CS49400 Audio Decoder DSP is targeted as a market-
specific consumer entertainment processor for AV Receivers
and DVD Audio/Video Players. The device is constructed using
an enhanced version of the CS49300 Family DSP audio
decoder followed by a 32-bit programmable post-processor
DSP, which gives the designer the ability to add product
differentiation through the Cirrus FrameworkTM programming
structure and Framework module library. Dolby Digital Pro
Logic II, DTS Digital Surround, MPEG Multichannel, and Cirrus
Original Surround 6.1 PCM Effects Processor (capable of
generating such DSP audio modes as: Hall, Theater, Church)
are included in the cost of the CS49400 Family DSP. Additional
algorithms available through the Crystal WareTM Software
Licensing Program, give the designer the ability to further
deliver end-product differentiation.
The CS49400 contains sufficient on-chip SRAM to support
decoding all major audio decoding algorithms available today
including: AAC Multichannel, DTS 96/24, DTS-ES 96/24. The
CS49400 also supports a glueless SDRAM/SRAM for
increased all-channel delays. The SRAM interface also
supports connection to an external byte-wide EPROM for code
storage or Flash memory thus allowing products to be field-
upgradable as new audio algorithms are developed.
This chip, teamed with Crystal WareTM certified decoder
library, Cirrus digital interface products and mixed signal data
converters, enables the conception and design of next
generation digital entertainment products.
