I am doing performance test on OMAP-L137 and DSK6713. the codebase is the same, it is only c source code, it contains alot of function call, if statements and switch statements, but doesn't do many DSP calculations. The optimization are set to level 3 for both DSP boards.
the clock for OMAP-L137 is 300MHz, and DSK6713 is 225MHz. I measure the performance by switching LED, and the JTAG is connected to the boards when measuring. The result is:
9us for one loop on DSK6713
28us for one loop on OMAP-L137
the DSK6713 it is about 3x faster then OMAP-L137 for my code. I what to know whether it is OK or not.
