The SNL320 is a high performance 16-bit
DSP base processor with 16MIPS CPU power.
The internal 64K words hi-speed ROM already
built-in a hi-performance software voice
synthesizer to provides lot of voice effects.
Such as hi-decompression engine to support
from 1.5kbps ~ 29kbps compression rate
for speech and music, multi-channel voice
synthesizer to provides 12-channel wave-table
melody. The voice combination is show
below: a. 1.5Kbps ~ 29Kbps + 4-channel
wave-table melody. b. 1.5Kbps ~ 29Kbps
+ 10Kbps ~ 29Kbps. c. 1.5Kbps ~ 29Kbps
+ 4-channel PCM file. The standard microprocessor
interface allows SNL320 to extend its
memory capability, or connect external
device. The SNL320 also built-in a Low
Voltage Detector circuit for power management
and a USB 1.1 interface for communication
with PC.
