The Joint Test Action Group (JTAG) is an electronics industry association formed in 1985 for developing a method of verifying designs and testing printed circuit boards after manufacture.
TCK is the JTAG clock signal. The other JTAG signals (TDI, TDO, TMS) are synchronous to TCK. So TCK has to toggle for anything to happen (usually things happen on TCK's rising edge). TMS. Inside each JTAG IC, there is a JTAG TAP controller. On the figure above, that means that there is a TAP controller in the CPU and another in the FPGA. The TAP controller is mainly a state machine with 16 states.
