UM017105-0511 Program Configurations

Zilog Developer Studio II – ZNEO™

User Manual

323

In this respect, this configuration obviously is very similar to the Copy to ERAM Program

Configuration discussed in Copy to ERAM Program Configuration

– see page 318. The

main difference is that RAM is typically internal memory, while ERAM is external.

Therefore, to use the Copy to ERAM Program Configuration, you must provide external

memory and configure its interface. By using the Copy to RAM Program Configuration,

you avoid that work. On the other hand, the amount of internal memory is rather limited

on many ZNEO devices, so the Copy to RAM Program Configuration might tend to be

limited to small applications or portions of applications during development.
