which one can i use???????????????????

Hello,

i am a researcher in the field of the power electronics and power system and i need a DSP to get output pulses to my switching devices like GTO,MOSFET,..........

the switching frequency may be 600MHZ so i am in need for a recommendation for a specified Type(single core or multicore   ,  series and number ) of the DSP which can do this function with high quality.

Thanks alot
