👉 The term "fenestrule" is a term used in the field of computer architecture to describe an element that serves as a logical gate or control unit. In digital circuits, a fenestrule is often used to implement a logic gate or control unit for controlling the flow of data through a circuit. Fenetrules can be either single-input/single-output (SISO) or multi-input-single-output (MISO) gates and are commonly found in computer systems where multiple outputs need to be controlled by
