Smaller chips sound sweeter

For ultra-compact processing of high-definition audio meeting standards including HD-DVD and Blu-ray, Freescale Semiconductor has created the Symphony audio DSP56720 and DSP56721 processors consolidating processing for the latest decoding standards with advanced postprocessing on the same chip.

Both devices feature dual DSP56300 24-bit cores, capable of 200 MIPS and 200MHz to meet the performance requirements of high-definition audio standards including DTS-HD, Dolby® Digital+ and Dolby TrueHD.

With large, integrated memories these devices also eliminate the need for external memory in most consumer applications, enabling a singlechip offering that delivers a simple and cost-effective solution.

The Symphony DSP56720 adds an external memory interface for audio applications that use external memory to accommodate long delays such as reverbs and lip sync.

Both devices are code-compatible with existing Freescale 24-bit DSP solutions. They also incorporate the same plug-and-play software architecture that exists in the Freescale DSP563xx family, allowing fast and easy migration to the higher-performance solution. In addition to supporting the standard audio decoders, the new processors also enhance flexibility through customisation of post-processing algorithms.
