Pulse generator - FPGA or µC?

[mz17]

Hey guys!

I am planning to build a TTL pulse generator, but i dont really know wheather to construct it in a FPGA system or with a Mircocontroller.

The pulse generator should be able to give out 8 pulse trains with independent frequencies simultanously (the pulse frequencies range about 5-15 kHz) and programmable delays.
However, i have to trgger one device that requires a TTL pulse rise time of max. 20 ns. So my pulses should be able to rise very fast.

To do think I should use a FPGA board, or is it smarter to go with a microcontroller?

U can also think of a CPLD

The pulse frequency is relatively low, the microcontroller should be completed, and also good control.
