Developers and systems designers creating advanced consumer audio products can now leverage the low cost, high performance and board space advantages of Freescale’s Symphony multicore DSP56720 and DSP56721 digital signal processors (DSP).

Designed to meet demand for increased memory and performance in audio applications, the multicore devices support a range of high definition audio standards and enable excellent audio experiences for end users of car infotainment systems, A/V receivers, professional audio equipment and more.

The DSP5672x products are designed to eliminate the need for multichip solutions by incorporating two 24-bit DSP56300 cores with 48-bit double precision capability, which handle advanced post processing and the latest decoding standards on the same chip. Across the two cores, the chip completes 400 MIPS and has 400 MHz total processing power, enabling the DSPs to meet the audio performance requirements of today’s advanced entertainment solutions.

With the demand for high definition video comes the demand for high definition audio. Consumers want to be immersed in the action with a realistic surround sound experience. High definition audio standards such as DTS-HD ﾭMaster Audio, Dolby Digital Plus and Dolby TrueHD are more complex than previous standards and the DSP56720 and DSP56721 are designed to support these high performance technologies and provide for potential future improvements.

The DSPs feature 248 K x 24-bit words of integrated memory. The DSP56720 adds an external memory controller to give the option for expanding memory off-chip or to interface to external parallel peripherals. Both DSPs integrate an S/PDIF transceiver and a 10-channel asynchronous sample rate converter. Additionally, the direct memory access (DMA) controller has been expanded to support up to eight DMA channels per core for higher bandwidth and more processing.
