Re: [hatari-devel] Code execution discontinuities and detecting them?

Hi Eero,

Just a quick note on DSP interrupts - if you are looking for test material you'll probably find it in audio applications where it's being used to buffer samples/DCTs from main memory, or perhaps output to the CODEC in a time-sensitive manner. Probably also in some demos which depend on this kind of behaviour for MP2 music, 3D vertex data streaming etc.

(Unfortunately you won't find anything like this in my project as the DSP is used more like a conventional processor / GPU with a simple host-based command structure and mostly very small, separate packets of data).

1. Can there be another exception while current one is being handled?

2. Will RTI return to previous exception previous handler, if it had
   not finished (instead of e.g. terminating all exceptions being handled
   at the moment)?
