how can I increase the CPU_CLOCK( processor speed ) to the maximum .
which are the registers to be configured with values?
in which file and how should I configure these registers

So... short answer is 'no'. Long answer is 'NOOOOOOOOOOOOOOO'.

Longer answer is actually a question: What precisely are you trying to achieve? As a general rule, all our modules are running as close as possible to max frequency as their PLLs will allow.

how can I find the processor usage for different tasks.
We have nearly 20tasks running on my project. These all tasks should
execute in every milliseconds.when but some are not being executed , what should I do ?

Look at the UCOS_TIME functions. Enable the UCOS_TIME macro and recompile the system. There's a function that will dump the usage of all running tasks. Note: these functions do not take into account time spent in interrupts. It only examines when tasks are scheduled in and out.

Its not completely clear from your post what the situation really is. Do some of your tasks not execute at all, or are they all executing but not fast enough? There is a difference between a round robin and a real-time operating system. In a RTOS the highest priority task ready to run will run. If some tasks are written in such a way that they do not block on anything, the lower priority tasks will not run, or not run as often as you need them to. Are you expecting round robing or rtos behavior from the OS?

Be careful if you're using a lot of tasks, there is a defined limit you have to modify if you go over 20 This crept up on me and the resulting problems did not make it obvious that this was the cause.

Good point. Also, if you have a lot of tasks that do a similar thing, such as checking network tcp sockets, a single task using the select() call could be much easier than having one task for each.
