Hi every1!
1>
I'm running a piece of code on target Cortex-a8 on ARM Profiler 2.0 using RTSM. The profile analysis that I get doesn't show any instance of dual issue. I'm aware of the bottlenecks in case of dual issue i.e. only certain combinations can be dual issued. But in my case I'm not able to find even a single instance of dual issue happening. Could any1 suggest the cause behind it?
2>RVD: When I select Cortex-a8.dll while selecting the target on rv debugger, multiple emulation baseboard gets displayed in the right pane. I'm confused out of those, which baseboard will be suitable for embedded applications. Could anybody clarify on this?

thanks for your replies.... i need further assistance
I am trying to run a particular project on
1.arm profiler 2.0(using rtsm) and
2. rtsm using rvd 4.0 (using performance counters)
Both experiments on Cortex-a8. But the counts that i get is quite surprising. Count in 2 and count in case 1 were in ratio of 2:3. I expect them to be more or less same as both are being rum on rtsm model.
Could any1 clarify on this?
