Coefficient
Parameter
The CS4610/11 is based on the Cirrus Logic, Crys-
talClear Stream Processor (SP) DSP core. The SP
core is optimized for digital audio processing, and
is powerful enough to handle complex signal pro-
cessing tasks such as Dolby AC-3 decoding
(CS4610 only) with ease. The SP core is supported
by a bus mastering PCI interface and a built-in ded-
icated DMA engine with hardware scatter-gather
support. These support functions ensure extremely
efficient transfer of audio data streams to and from
host-based memory buffers, providing a system
solution with maximum performance and minimal
host CPU loading.
The all-digital CS4610/11 supports a variety of au-
dio I/O configurations, including direct connection
to the CrystalClear CS423x Codecs via a bi-direc-
tional serial data link, or direct connection to an
AC’97 Codec such as the CrystalClear CS4297.
