Number of Operating Cycles for DSP function

Base on my own understanding, the performance of a DSP processor is based on the operating freq as well as the algorithm used.
If what i understand is correct, is there any reference to check how many clock cycles is required for the functions of the DSP?
And is there any site where there is a whole list/library of DSP functions for reference?
Thanks in advance

Check the datasheet for the DSP you are using, as the number of clock cycles for each instruction will different for each family of device and can be different between devices within a given family.

For libraries, take a look at OpenDSP

I am unable to find the particular section.
i have attached the datasheet of the DSP which i am looking at.
I could only find the cycle for data transmission, but not about the functions in the DSP.
Have i been looking at the wrong set of datasheet?
or did i overlook any section in the data sheet?

Try the stuff referenced on page 99 of the linked PDF - the article "SPRUE02" has the processor instructions described in it.
