Freescale Semiconductor has announced that it is now shipping its Symphony DSP56720 and DSP56721 multicore audio processors. Introduced early last year, the DSP5672x products are designed to eliminate the need for multi-chip 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 chips offer 400 MIPS and have 400-MHz total processing power, supporting high-definition audio standards such as DTS-HD Master Audio, Dolby Digital Plus and Dolby TrueHD, as well as providing for potential future improvements. Both DSPs include 248K x 24-bit words of integrated memory, while the DSP56720 adds an external memory controller to give the option for expanding memory off-chip or to interface to external parallel peripherals.
Other features include an integrated S/PDIF transceiver and a ten-channel ASRC. Additionally, the DMA controller has been expanded to support up to eight DMA channels per core for higher bandwidth and more processing. The devices are code compatible with Freescale's existing 24-bit DSP solutions and incorporate the same plug-and-play software architecture used in the Freescale DSP563xx family.
The DSP56720 and DSP56721 are now shipping in volume quantities at a suggested resale price of $11.21 USD for the 144-pin LQFP in 10K unit quanties.
