A.R.Bayer DSP Systeme: audio processing module with SHARC, stereo audio, and S/PDIF
SHARC Module with stereo audio and S/PDIFThe SHARCaudio module is a very small, low-cost, audio processing 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 built-in S/PDIF interface allows to mix 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. Widely used 100 mil (2.54mm) pin headers are used to connect the module to a target board. A break-out board and a miniBSP are available for development purposes to get your project started quickly. 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 equipment.
The DSP can be controlled via its UART, I²C or SPI interface. These interfaces may also be used to control a keypad or an LCD display. An auxiliary 8-channel A/D converter can be used to control parameters using analog inputs rather than via a micro-controller. 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.
