Guillaume, It shouldn't take 25 cycles to execute a move like you describe. The simulator is cycle accurate so there is something else going on there. All the insturction timings are described in Appendix A of the 56300 Family Manual... -- dB --- GuillaumeDesj <> wrote: > Hi, > > I would like to use indirect addressing using the offset register on > the DSP56303 chipset. > > However, the simulator tells me that such an instruction takes 25 > clock cycles to execute !

Hi, I would like to use indirect addressing using the offset register on the DSP56303 chipset. However, the simulator tells me that such an instruction takes 25 clock cycles to execute ! I do not see any reason for it being this high, so i was wondering if this might be a simulator issue.... Also, while we're on the subject of clock cycles, does Motorola have a document listing the amount of clock cycles required by each instruction depending on the addressing modes, etc ? Thanks in advance, Guillaume
