Nios2 FPGA based profiler Airwolf AddressTrace implementation

Hello All, 

 

I am doing some research related to profiling and optimization of applications written for Nios 2 process using Altera FPGA. I know that gprof is available for profiling and it is a good tool to use. But I want to explore and compare other profiling and optimization tools as well. I have read some papers which have described the architecture of Airwolf and AddressTrace hardware based profilers but i have not find the implementation of these architectures anywhere for reference.  

 

If anybody has ever used any other good tool for optimization on nios2 please tell me. I am waiting for the replies. 

 

Thanks 

Amna
