Architectural Overview
The SAA7785 ThunderBird Avenger
TM
is a multi-functional device that provides sound processing producing Sound-
Blaster-compatible emulation, DirectSound acceleration, 3D sound, spatialization, special effects, and 64-voice wavet-
able synthesis through the use of a Pine Digital Signal Processor (DSP) as the primary engine. Included within the
ThunderBird Q3DIII are interfaces for an AC97 codec, I
2
S I/O, MIDI port, standard analog joysticks, and an S/P DIF
Consumer Output port.
