SHARCaudio

The SHARCaudio module is a very small, low-cost, audio processor system which can be operated in stand-alone or embedded applications. It comes with a powerful 200MHz (266MHz optional) SHARC DSP and a 24-bit stereo audio codec (> 100dB dynamic range) with line-in and line-out channels, an S/PDIF interface, I²C, UART and SPI for best connectivity.

The system was designed for use in high-end sound processing applications such as equalizers, feedback suppressors, limiters, effect processors, exciters and other studio and stage applications.

An auxiliary 8-channel A/D converter can be used to control parameters using analog inputs rather than via a micro-controller. Nonetheless, the DSP can be controlled via its UART, I²C or SPI interface. These interfaces may also be used to control a keypad or LCD display.

Using the S/PDIF interface, the module is capable of mixing audio sources from the analog and the digital domain.

With a size of only 1.0” x 2.0”, the board will fit every embedded application. The module can be mounted directly to the target via its SMT-pads or via optional 100 mil (2.54mm) pin headers. All special function pins (eight total) can also be used as general purpose I/O pins. Two FLAG pins are software programmable as either input or output.
