Tips about Special Projects

The tips about special projects in this chapter were collected from Motorola customers and

application developers engaged in “real world” projects.

4.1 Managing Projects with Multiple Devices

Both the Suite56 ADS debugger and the Suite56 simulator support your code generation

and debugging for multiple digital signal processors of the same family.

4.1.1 Connecting Multiple Devices to the Suite56 ADS Debugger

If you plan to use the Suite56 ADS debugger with multiple digital signal processors, you

must first consider whether or not the digital signal processors have a JTAG interface.

If your project involves multiple digital signal processors that do not have a JTAG

interface, then you need one command converter per device for debugging through a

Suite56 ADS debugger. You can connect as many as eight devices in this way. Using a

single 37-pin interface cable, splice the command converters to the host computer (your

development platform), and connect each command converter to one of the non-JTAG

digital signal processors through a 14-pin ribbon cable, as in Figure 4-1.
