Freescale: Symphony SoundBite - Affordable Audio DSP Development Kit

Kit Overview

Freescale introduces the Symphony SoundBite Development Kit, designed for cost-sensitive applications and college laboratories, providing a very low-cost entry point into high-end DSP solutions. The Symphony SoundBite development kit brings much of the performance of Freescale’s full-featured evaluation module (DSPAUDIOEVMMB1E motherboard and DSxP371DB1E daughtercard) for the Symphony DSP56371 digital signal processor to a more compact and userfriendly design at a very manageable price point.

The Symphony SoundBite is capable of simultaneously processing 8 independent channels of line-level audio via 4 pairs of 3.5mm stereo jacks. One input/output pair of jacks is shared with the AKM S/PDIF receiver and transmitter, enabling optical digital audio input and output. The analog processing is handled by four AKM 24-bit stereo codecs at sampling rates up to 192 kHz. Multiple banks of DIP switches and multi-colored LEDs connected to the DSP’s GPIO pins allow for user interaction with the DSP application.

The DSP56371 is capable of running delay management, bass management and DTS96/24 while using less than half of the DSP's computing capability. This enables designers to add system enhancements that the discerning audio consumer now expects. The performance increase is made possible through the use of a higher core frequency, fewer memory wait states, a larger amount of on-chip static random access memory (SRAM) and the addition of an Enhanced Filter Coprocessor (EFCOP). By removing the need for external high-speed SRAM and making smaller, less complex boards, the DSP56371 is performance-rich and cost-effective.

Key Applications: Digital audio compression/decompression, Sound field processing, Acoustic equalization and other digital audio algorithms.
