DSP56720/DSP56721 DSP56720 144-Pin LQFP 20 mm × 20 mm 0.5 mm pitch DSP56721 80-Pin LQFP 14 mm × 14 mm 0.65 mm pitch 144-Pin LQFP 20 mm × 20 mm 0.5 mm pitch Document Number: DSP56720EC Rev. 5, 02/2009 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. The DSP56720/DSP56721 devices are intended for 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. In addition, DSP56720/DSP56721 devices are optimal for the professional audio market requiring audio recording, signal processing, and digital audio synthesis. 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 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 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. The DSP56720/DSP56721 are high density CMOS devices with 3.3 V inputs and outputs. 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. Symphony™ DSP56720/DSP56721 Multi-Core Audio Processors |
