RE: [microblaze-uclinux] bechmarks




Rick,
Only thing I need the source code for a benchmark I can run with out uclinux installed.  I know I can use the one in the uclinux distribution once I get uclinux running. So overall what I am looking for is some source code that will compile and can be run directly on the powerpc and the microblaze on the memec board.

The issue I have is I have some benchmark that is running and is a drystone but I can not get the calculations correct for the timer.  Does anyone now how the opb_timer measures.  I am using the get command but what exactly is it returning since the data sheets do not really tell.  I thing if I can get an exact answer to this I can get it working.

Right now the best guess we have is that it measures clock cycles and runs at 100mhz or what ever speed the opb bus is running.  So ifthis is the case each clock cycle is equivalent to 10ns.  But not sure this is 100% correct.  Any help about the timer would be great.
Thank
Brett

If you do a search on the UQ web site for Dhrystones or Bogomips there are a lot of reports for different implementations. I think to remember my V2P7 board to perform near 60 DMIPS or 50 BogoMIPS at 100MHz.

[microblaze-uclinux] bechmarks

 

I was wondering if anyone had some benchmarks that will run on the microblaze processor.  Prior to placing uclinux on the board I would liek to benckmark the microblaze.  I need to run a benchmark on the microblaze and the ppc on a memec 2vp7 board for a paper to state some performance results between the 2.

Thanks
