SNC739中文產(chǎn)品介紹 :  
 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.
