channel decoding

In system programmable Flash, capable of 
holding 16 DSP programs

Description

The CRD42528 is a reference design for the CS49300
DSP family and the CS42528 CODEC. It supports up to
8 channels of analog input at 48 and 96 kHz, or
2 channels of analog input at 192 kHz. One of four
digital S/PDIF inputs may be selected. Additionally, up
to 2 channels of digital S/PDIF output and 8 channels of
analog output at up to 192 kHz are supported. The on
board SRAM is included to allow for AAC 5.1 discrete
channel decoding, and on-board flash memory is
included to allow in-system programming of up to
16 DSP images. The DSP supports the following
algorithms, including (but not limited to) AAC, Dolby
Digital (AC-3), Dolby Digital EX, DTS, DTS-ES, DTS
Neo:6, Cirrus Original Surround (including COS 6.1),
SRS CircleSurround, SRS TruSurround, Pro Logic II,
MPEG Multichannel (including EX), and HDCD.

The control interface to the CRD42528 is the UDSP
System Platform. All control and data I/O is connected
to headers, which allows the CRD42528 to be used
easily in a end system or as a reference design. A larger
block diagram is shown on the next page.
