2008-01-11 05:57:18     Any options or methods in uclinux to reduce latency

Message: 49476    hi all

 

We are working with mpeg codec applications and the target is bf561.

As the project is in final stage,we have started the optimization and looking to reduce the latency occured by our application.

Is there any specific method or option in uclinux kernel to do this task?

It would be great help for us if you provide any ideas regarding this..

 

thanks

I'm not sure what you mean by latency. Latency == delay. How is there delay in your application?

hi

 

Actually our need is to reduce the execution time of application.The latency i mean was the time taken by the board to produce the output.So what are the kernel optimization methods available in uclinux?

 

thanks

This is still very unclear. There are things you need to do before optimization:

 

1. measure your current "latency"

2. identify bottle neck

3. optimize
