SNC710
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 2 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.
