Programmable Array Logic Structure. Programmable array logic is a family of programmable logic device semiconductors used to implement logic functions in digital circuits introduced by monolithic memories inc. However it is to be noted that here only the and gate array is programmable unlike the or gate array which has a fixed logic.
Design of programmable array logic pal the definition of term pal or programmable array logic is one type of pld which is known as programmable logic device circuit and working of this pal is the same as the pla. The following figure shows the internal structure of programmable array logic. It has programmable and array and fixed or array.
The designing of the programmable array logic can be done with fixed or gates as well as programmable and gates.
The fundamental components of plas are input buffer programmable and gate matrix and programmable or gate matrix. The designing of the programmable array logic can be done with fixed or gates as well as programmable and gates. Programmable array logic pal is a commonly used programmable logic device pld. It has programmable and array and fixed or array.
