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.
