DSP56725 Multi-Core Audio
The Symphony DSP56724/DSP56725 Multi-Core Audio
Processors are part of the DSP5672x family of programmable
CMOS DSPs, designed using dual DSP56300 24-bit cores.
The DSP56724 is intended for consumer and professional
audio applications that require high performance for audio
processing. In addition, the DSP56724 is ideally suited for
applications that need the capability to expand memory
off-chip or to interface to external parallel peripherals.
Potential applications include A/V receivers, DVD Receivers,
Home Theater in a Box (HTIB), and professional audio
equipment including portable recording equipment, musical
instruments, guitar amplifiers and pedals. The DSP56724
offers customers flexibility in their designs by providing a
more cost-effective alternative to the DSP56720 while
maintaining pin compatibility.
The DSP56725 is intended for automotive and audio
applications that require high performance for audio
processing. Potential applications include A/V receivers,
DVD Receivers, Home Theater in a Box (HTIB), and
automotive amplifiers and entertainment systems. The
DSP56725 offers customers flexibility in their designs by
providing a more cost-effective alternative to the DSP56721
while maintaining pin compatibility.
The DSP56724/DSP56725 devices provide a wealth of
on-chip audio processing functions, via a plug and play
software architecture system that supports audio decoding
algorithms, various equalization algorithms, compression,
signal generator, tone control, fade/balance, level
meter/spectrum analyzer, among others. The
DSP56724/DSP56725 devices also support various matrix
decoders and sound field processing algorithms.
With two DSP56300 cores, a single DSP56724/ DSP56725
device can replace dual-DSP designs, saving costs while

meeting high MIPs requirements. Legacy peripherals from
the previous DSP5636x/37x families are included, as are a
variety of new modules available in the DSP5672x family.
Modules from the DSP56720 are included, such as an
Asynchronous Sample Rate Converter (ASRC), an Inter-Core
Communication (ICC) module, an External Memory
Controller (EMC) to support SDRAM (DSP56724 only), and
a Sony/Philips Digital Interface (S/PDIF) transceiver.
The DSP56724/DSP56725 devices offer up to 250 million
instructions per second (MIPs) per core using an internal
250 MHz clock. The DSP56724/ DSP56725 products are high
density CMOS devices with 3.3 V inputs and outputs.
The DSP56724 block diagram is shown in Figure 1; the
DSP56725 block diagram is shown in Figure 2.
