SAM9703 General Description

The highly-integrated architecture of the SAM9703 device combines a specializedhigh-performance RISC digital signal processor and a general-purpose 16-bit CISCcontrol processor on a single chip. An on-chip memory management unit allows thedigital signal processor and the control processor to share external ROM and RAMdevices. The ROM bus width should be 16 bits, while the SRAM can be selected to be8 or 16 bits wide. When using an 8-bit SRAM, fast type (static cache) should beselected as two SRAM cycles will be done in one ROM cycle duration.

Running at 300 million operations per second (MOPS), the digital signal processorsupports high-quality PCM synthesis as well as most important functions like reverb,chorus, surround effect and equalizer. By adding an additional stereo DAC, four-channel audio surround can be obtained as well.

Computer karaoke manufacturers will enjoy the built-in high-quality dual-microphoneecho processing.

he firmware can also be modified to fit customer specifica-tions. A SAM9703-based development/prototyping board isavailable and includes the SAM9703, 32 Mbits of EPROMmemory, 32K words of SRAM, a codec and one DAC, pro-viding four channels of audio out and a stereo line inputref. 9703DVB).

The SAM9703 internal sound definition format is compati-ble with the SAM9407 sound studio IC. Therefore it ispossible to develop specific sounds for the SAM9703 byusing the development tools of the SAM9407.

The SAM9703 operates from a "low" frequency 9.6 MHztypical crystal. A built-in PLL raises this frequency to a 38.4MHz internal clock which controls the two processors. Carehas been taken that output pin signals change only whennecessary. This minimizes RFI (radio frequency interfer-ences) and power consumption. Minimizing RFI is mostlyimportant in order to comply with standards such as FCC,CSA and CE.

The core power supply for the SAM9703 should be 3.3V ±10%, while the periphery supports supply from 3V to 5.5V(5V ± 10% for TTL-compatible applications). Therefore, byselecting 3.3V ROM, SRAM and DAC, it is possible todevelop low-power/low-voltage portable applications

Dream® licenses a 32-Mbit jumper-configurable firmware ROM, CleanWave32®,which includes high-quality General MIDI-compliant synthesis with many additionalsounds and drumsets. Please refer to the corresponding CleanWave32® datasheet.

Other sample sets are available under special conditions.More information, including licensing, can be obtained from any Atmel sales office.Smaller capacity firmwares are also available for more cost-sensitive or portableapplications.

SAM9707 General Description

The SAM9707 is a highly integrated sound processor studio that combines a special-ized high-performance RISC-based digital signal processor(synthesis/DSP) and ageneral-purpose 16-bit CISC-based control processor on a single chip. An on-chipmemory management unit (MMU) allows the synthesis/DSP and the control processorto share external ROM and/or RAM memory devices. An intelligent peripheral I/Ointerface function handles other I/O interfaces, such as the ISA PC bus, the on-chipMIDI UART and the codec control interface, with minimum intervention from the con-trol processor.
