The
SNC7001 is a multi-function voice engine,
which is based on 16-bit fixed-point DSP architecture.
This chip embedded 32K words hi-performance
internal program RAM (boot from external flash,
only one time after IC reset) and 16K words
RAM (8K program RAM “boot from external flash,
update anytime by user program” and 8K data
RAM). 32K words internal program RAM is used
to implement software synthesizer in order
to provide various high speed image, voice
compression or many different fancy algorithm
for users, such as 1.5kbps~32kbps voice compression,
12-CH wave-table melody, voice changer algorithm
etc…. Furthermore, the SNC7001 also built-in
many interfaces for connecting with external
devices, such as USB2.0, SD card, NAND Flash,
SPI, I2S, LCM, CMOS sensor etc…, these interfaces
can create more advanced application at different
areas in the future. .
