24-bit Dual-Core Symphony^® DSP

Responding to the demand for increased memory and performance in advanced audio applications, NXP^® has designed digital signal processing (DSP) chips that support multiple high-definition (HD) audio standards. The Symphony™ audio DSP56720 represents the first in a complete family of multi-core 24-bit processors from NXP, further broadening the company's expansive audio portfolio. The DSP56720 retains code compatibility with Our popular DSP56000 and DSP56300 core families of DSPs while enhancing its capabilities with many new features such as integrated S/PDIF module, an external memory controller, an embedded asynchronous sample rate converter and more audio channels.

The Symphony^® audio DSP56720 excels at audio processing for consumer and professional audio applications requiring high million instructions per second (MIPS).For consumer applications, higher MIPS and memory requirements are driven by the new HD audio standards (Dolby® Digital Plus, Dolby® TrueHD, DTS-HD). The DSP56720 also provides an external memory controller to expand memory off-chip to support lip sync delays required by some consumer applications.

For professional audio applications which require audio recording, signal processing and digital audio synthesis, the DSP56720 offers a solution with high performance without sacrificing on cost or power consumption and can replace a multi-DSP design with a single chip solution.

The DSP56720 provides a wealth of on-chip audio processing functions, via a plug and play software architecture system which has the ability to support audio decoding algorithms as well as various post processing functions.
