Chapter I on combinational circuits

PLD. A programmable logic device is an electronic component used to build reconfigurable digital circuits. Unlike a logic gate, which has a fixed function, a PLD has an undefined function at the time of manufacture. Before the PLD can be used in a circuit it must be programmed, that is, reconfigured.

Chapter II on sequential systems

FSM. A Finite State Machine is a mathematical model of computation. It is an abstract machine that can be in exactly one of a finite number of states at any given time. The FSM can change from one state to another in response to some external inputs and depending of its current internal state; the change from one state to another is called a transition. An FSM is defined by a list of its states, its initial state, and the conditions for each transition. Source Wikipedia.


Chapter III on  microcontrollers

 mC or MCU. A microcontroller unit is a is a small computer on a single integrated circuit. Source Wikipedia.
