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 Framework TM 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 Ware TM 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...
