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.
