FM801-AU
PCI Audio Controller
The ForteMedia FM801-AU is designed to
suit the most cost-effective, practical, PCI
Audio solution for both desktop computer
and notebook computer. It integrates the
essential features of today’s gaming
requirements without compromising the
PC98 criterion for audio quality. FM801-AU
integrates the PCI 2.2 bus master controller,
music synthesis, SoundBlaster Pro Engine,
sampling rate converter, digital mixer,
CODEC interface, game ports, I2S ports and
S/PDIF port. The FM801 solution leverages
its simple but effective hardware/software
architecture and the uprising HSP (host-
based signal processing) support on Direct
Sound, WaveTable and Direct 3D positional
audio, and is therefore the most practical
PCI audio solution. The CODEC interface
is fully compliant to AC-97 ver.2.1 and is
capable of supporting multiple speakers for
either docking application or merely a PC
theater set up for gaming and audio
enjoyment. With its 3.3 volts operating
voltage, ACPI power management, PME
and PCI clock-run supports, plus a small
100-pin PQFP package size, the FM801
surely is the right choice for today’s PCI
audio solution.

FM801-AU
PCI Audio Controller
Architecture
FM801-AU is a cost effective, highly integrated PCI audio controller for today’s
high performance multimedia PC audio requirements. Based on ForteMedia’s own
proprietary DOS game interface, hardware MIDI synthesis engine and high
bandwidth PCI interface, FM801-AU supports games under both Microsoft
Windows and DOS environments without compatibility issues. With its low cost
structure and support high sound quality AC97 architecture along with the assured
game compatibility, the FM801-AU is the desired PCI audio solution. FM801-AU
can be physically partitioned into the following functional blocks:
• PCI Interface
• FM synthesizer
• Legacy DOS Game Engine, MIDI Port and Game Port
• Peripheral Interfaces (I2S, VOL, GPIOs and SPDIF, EEPROM)
• AC97 CODEC Interface, SRC and Digital Mixing
