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

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

Freescale reserves the right to change the detail specifications as may be required to permit

improvements in the design of its products.
