OVERVIEW

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.

Legacy Audio block supports FM Synthesizer, Sound Blaster Pro, MPU401 UART mode and Joystick

function in order to provide hardware compatibility for numerous PC games on real DOS without any software

driver. To achieve legacy DMAC compatibility on the PCI, DS-1S supports both PC/PCI and Distributed

DMA protocols. DS-1S also supports Serialized IRQ for legacy IRQ compatibility.

DS-1S supports the connection to AC’97 which provides high quality DAC, ADC and analog mixing, and it

can connect two AC’97s. In addition, it supports consumer IEC958, Audio Digital Interface (SPDIF), to

connect external audio equipment by digital.
