The Symphony DSP56720/DSP56721 Multi-Core Audio  
Processors are part of the DSP5672x family of programmable  
CMOS DSPs, designed using multiple DSP56300 24-bit  
cores.

automotive, consumer, and professional audio applications  
that require high performance for audio processing. In  
addition, the DSP56720 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, HD-DVD and Blu-Ray players, car

audio/amplifiers, and professional recording equipment.  
The DSP56720/DSP56721 devices excel at audio processing  
for automotive and consumer audio applications requiring  
high MIPs. Higher MIPs and memory requirements are driven  
by the new high-definition audio standards (Dolby Digital+,  
Dolby TrueHD, DTS-HD, for example) and the desire to  
process multiple audio streams.  
Communication (ICC), an External Memory Controller  
(EMC) to support SDRAM, and a Sony/Philips Digital  
Interface (S/PDIF).  
The DSP56720/DSP56721 offer 200 million instructions per  
second (MIPs) per core using an internal 200 MHz clock.  
In addition, DSP56720/DSP56721 devices are optimal for the  
professional audio market requiring audio recording, signal  
processing, and digital audio synthesis.  
The DSP56720/DSP56721 are high density CMOS devices  
with 3.3 V inputs and outputs.  
The DSP56720/DSP56721 processors 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  
The DSP56720 device is slightly different than the DSP56721  
device—the DSP56720 includes an external memory  
interface while the DSP56721 device does not. The  
DSP56720 block diagram is shown in Figure 1; the  
DSP56721 block diagram is shown in Figure 2.  
DSP56720/DSP56721 devices also support various matrix  
decoders and sound field processing algorithms.  
With two DSP56300 cores, a single DSP56720 or DSP56721  
device can replace dual-DSP designs, saving costs while  
meeting high MIPs requirements. Legacy peripherals from  
the previous DSP5636x/7x families are included, as well as a  
variety of new modules. Included among the new modules are  
an Asynchronous Sample Rate Converter (ASRC), Inter-Core

improvements in the design of its products.
