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 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 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.  
NOTE  
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.  
This document contains information on a new product.  
Specifications and information herein are subject to change  
without notice. Finalized specifications may be published  
after further characterization and device qualifications are  
completed.  
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
