Description
The highly-integrated architecture of the ATSAM9703 device combines a specialized
high-performance RISC digital signal processor and a general-purpose 16-bit CISC
control processor on a single chip. An on-chip memory management unit allows the
digital signal processor and the control processor to share external ROM and RAM
devices. The ROM bus width should be 16 bits, while the SRAM can be selected to be
8 or 16 bits wide. When using an 8-bit SRAM, fast type (static cache) should be
selected as two SRAM cycles will be done in one ROM cycle duration.
Running at 300 million operations per second (MOPS), the digital signal processor
supports high-quality PCM synthesis as well as most important functions like reverb,
chorus, surround effect and equalizer. By adding an additional stereo DAC, four- chan-
nel audio surround can be obtained as well.
Computer Karaoke manufacturers will enjoy the built-in high-quality dual-microphone
echo processing.
Dream® licenses a 32-Mbit jumper-configurable firmware ROM, CleanWave32™,
which includes high-quality General MIDI-compliant synthesis with many additional
sounds 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 firmware is also available for more cost-sensitive or portable
applications.
