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 PC/PCI and Distributed DMA protocols. DS-1S also supports Serialized IRQ for legacy IRQ compatiblity. DS-1S supports the connection to AC '97 which provides high quality DAC, ADC and analog mixing. In addition, it supports consumer IEC958, Audio Digital Interface (SPDIF), to connect external audio equipment by digital.
