What is the name of the clock divider?
Clock Divider is also known as frequency divider, which divides the input clock frequency and produce output clock.

How is clock division done in a FPGA?
In industry, most of clock division happens either through PLL (Phase-locked-loop) in ASIC and through DCM (Digital-Clock-Manger) in FPGAs. Once clock is available, its possible to have a simple synchronous clock division through few Combinational Gates and D-Flops.
Which is better clock divider or clock pin?
As clear the design with the “discrete” clock divider is in line with the timing performances of the design taking the clock from the dedicated pin, moreover, the design with clock divider has slightly better performances!
How to implement clock divider without the reset signal?
Implementing the divider without the reset signal, you shall set the initial condition to clk_counter signal during the declaration of the signal itself: Remember that this VHDL code it is still synthesizable, so you can use it without any problem, but your clock divider start condition is unknown.
Can a clock divider be used as a wraparound counter?
You can think about at the clock divider by two, as a wraparound counter where the Least Significant Bit (LSB) is used to generate the clock. The counter LSB flips at half the clock rate, this means that it can be used as clock divider by two. What happen to the others bit?
