SNC710
16-bit Voice Engine
1. INTRODUCTION
The SNC710 is a powerful voice engine, which is based on16-bit fixed-point DSP
architecture. This chip embedded 32K words hi-performance ROM and 2K words
RAM. This internal ROM is used to implement software synthesizer in order to provide
various flexible sound effects for users, such as 2kbps~24kbps voice compression,
4-CH wave-table melody etc…. Furthermore, the SNC710 also built-in a SONiX’s
mask ROM interface, all the user’s program and voice data should be stored in
external mask ROM. And SNC710 can execute user’s program from this external
mask ROM.
