Figure-1

The SNC710 is a ROM-less DSP architecture, but it still built-in 32K hi-speed ROM for

software voice synthesizer. All the user’s program and voice data are stored in

external mask ROM that provided by SONiX. In Figure-1, show out the system

connection between SNC710 and external mask ROM. Each mask ROM both has

several bank select pins (BSn) to specify the memory region, and SNC710 allows user

to connect totally 4 external mask ROMs.

The SNC710 built-in an 8-bit AD (address/data) bus, which connect to SONiX’s mask

ROM. And SONiX’s mask ROM provides encryption code function to protect user’s

program to avoid illegal copy. In SONiX’s compiler system, user can assign his own

ID-Code to protect his program and data.
