Abstract: Provided is a variable electronic apparatus including a memory unit, a processing unit and a programmable logic gate device. The memory unit stores configuration data. The processing unit reads the configuration data from the memory unit and determines at least one control mode based on the configuration data. The programmable logic gate device includes a plurality of function modules and at least one switching unit. When the control mode includes a function module selecting mode and a signal line switching mode, the processing unit selects or activates the function modules of the programmable logic gate device based on the function module selecting mode, and the switching unit of the programmable logic gate device dynamically modifies or adaptably adjusts a bus of the function module selected by the processing unit and a corresponding external signal line based on the signal line switching mode.
