WinSystems' PC/104-Plus Audio Accelerator Module Provides a Sound Solution for Embedded Systems


March 13, 2002 - Embedded Systems Conference, San Francisco, CA -Today, WinSystems introduced the first PC/104-Plus SoundBlaster Pro(TM) compatible audio board. Dubbed the PPM-Audio, it provides high-quality voice and sound reproduction for embedded systems. It can record, compress, store, and playback voice, sound, and music. An extensive selection of audio inputs and outputs on multiple I/O connectors make the PPM-Audio easily adaptable to various application configurations. The PPM-Audio module is small, measuring 90 x 96 mm (3.6- x 3.8-in.), and is PC/104-Plus compliant for space-limited industrial designs.

Based upon the ESS Technology (Fremont. CA) ES1980 Maestro-3 chip, the PPM-Audio includes an advanced audio signal processor that provides simultaneous support for multiple audio streams. With the built-in DSP core, the ES1980 uses its dedicated DMA engine to handle complex signal processing tasks with a bus-mastering PCI interface that connects directly to the PC/104-Plus bus. The support functions ensure efficient transfer of audio data streams to and from system memory buffers, providing a system solution with maximum performance and minimal host CPU loading. The audio accelerator removes the processing overhead from the host CPU which reduces cost, improves performance, and permits extended temperature operation since a less power-hungry CPU can be used.

There are seven external I/O sources for the board. They are Microphone Input, Line Input, CD Input, Auxiliary Input, Joystick, Line Output, and Speaker Output. The speaker amplifier is rated at 2 Watts per channel into an 8 ohm load. Line inputs are volt peak-to-peak.

The module is designed to work with x86-compatible single board computers that support PC/104-Plus expansion. It is compatible with Windows(TM) SoundSystem(TM) and also supports DOS legacy audio programs.

The PPM-Audio requires +5volts DC to operate and draws 225 mA (typical).
