Re: [hatari-devel] Falcon cpu/dsp emu issue?

[Douglas Little <doug694@xxxxxxxxxxxxxx>]

Only polling is used. TimerC on CPU side is used for measuring MIPS using fixed number of DSP operations - but the DSP communications are all manually done via host port.

Hi

I can get the same problem with your dspbench.tos when using CE. It works with/without cpu prefetch mode, but stalls in CE mode.

It could also be an interrupt problem, as it's handled differently in CE mode and there was quite some change there. Do you use DSP interrupt vector (on the MFP side) or are you only polling the dsp registers ?
