Q: What is a PGA?
A: At the moment, cgminer supports 3 FPGA's: Icarus, Ztex and BitForce.
A: At the moment, cgminer supports 4 FPGAs: BitForce, Icarus, ModMiner, and Ztex.
They are Field-Programmable Gate Arrays that have been programmed to do Bitcoin
mining. Since the acronym needs to be only 3 characters, the "Field-" part has
been skipped.
