You can find details about changing TMS320C5502 clock frequency in the Data manual section 3.10.4 Changing the Clock Group Frequencies at:
www.ti.com/.../tms320vc5502.pdf
Also you can find description of PLL Divider 0 Register fields in section 3.10.5.3 PLL Divider 0 Register (PLLDIV0).

Hamza,

You will have to modify the GEL file to manipulate the CPU frequency.
processors.wiki.ti.com/.../GEL

The C5502 Gel is located at C:\ti\ccsv7\ccs_base\emulation\boards\evm5502\gel\sd5502evm.gel
