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 95Â® DirectSoundÂ®,

DirectSound3DÂ®, 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 â97 Codec.

PC/PCI, DDMA, and CrystalClear Legacy support

provide PCI-only legacy games compatibility.
