DESCRIPTION
The CS4614 is a high performance pin-compatible
upgrade to the 100-pin CS4610/11 PCI audio ac-
celerator. With the added legacy compatibility
modes, the CS4614 enables real mode DOS com-
patible PCI-only audio subsystems. This device,
combined with application and driver software,
provides a complete system solution for hardware
acceleration of Windows 95® DirectSound®,
DirectSound3D®, DirectInput, and Wavetable Syn-
thesis. WDM drivers provide support for both
Windows 98 and Windows NT 5.0.
The CS4614 is based on the Cirrus Logic Crystal-
Clear 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 with ease. The SP core is supported
by a bus mastering PCI interface and a built-in
dedicated 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 CS4614 supports a variety of audio
I/O configurations including direct connection to
the CrystalClear CS4297 AC ‘97 Codec.
PC/PCI, DDMA, and CrystalClear Legacy support
provide PCI-only legacy games compatibility.
