CS4630

CS4630 CrystalClear™ SoundFusion® PCI Audio Accelerator Features l Description SLIMD™ The CS4630 is a high performance upgrade to the CS4624 PCI audio accelerator. With support for legacy compatibility modes, the CS4630 enables real mode DOS compatibility within PCI-only audio subsystems. This device, combined with application and driver software, provides a complete system solution for hardware acceleration of Microsoft’s DirectSound, DirectSound3D, DirectInput, and Wavetable Synthesis. WDM drivers provide support for both Windows 98® and Windows 2000®. The CS4630 is based on the Cirrus Logic CrystalClear™ Stream Processor (SP) DSP core. The SP core is optimized for digital audio processing, and is powerful enough to handle complex signal processing tasks such as Sensaura 3D, 4-channel output, and hardware wavetable synthesis. 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.
