Are programs copied from flash to ram to execute, or are they XIP and only use RAM for stacks, variable storage, etc.?

Good point. It makes no sense at all.
I will have to register myself in one of the Casio/Texas specialized forums to ask about this subject there.

My pure guess is that the 8MByte SDRAM are not used to run the Basic like programs, as the processor itself would have internal very fast SRAM big enough to accommodate the 61KByte user programming area.
However all the other builtin and added apps would need to be loaded to and also use the medium fast 8MByte SDRAM as a scratch workarea.

Again, this is total guessing work, as the more I read on Casiopeia and TI Planet forums the more confused I get (not because I can't read and understand French, because I do. Many folks there have deep understanding of the Casio CPU architecture and don't bother to document the basics such as this subject).
