Part Name(s) : YMF744B YMF744B-R YMF744B-V Yamaha
Yamaha Corporation
Description : 3.3V; DS-1S high performance audio controller for the PCI bus

YMF744B (DS-1S) is a high performance audio controller for the PCI Bus. DS-1S consists of two separated functional blocks. One is the PCI Audio block and the other is the Legacy Audio block. PCI Audio block allows Software Driver to handle maximum of 73 concurrent audio streams with the Bus Master DMA engine. The PCI Audio Engine converts the sampling rate of each audio stream and the streams are mixed without utilizing the CPU or causing system latency. By using the Software Driver from YAMAHA, PCI Audio provides 64-voice XG wavetable synthesizer with Reverb and variation. It also supports DirectSound hardware accelerator, Downloadable Sound (DLS) and DirectMusic accelerator.
