Programmable Logic Array Block Diagram. The pal architecture consists of two main components. Each input has a buffer gate and an inverter gate.
It has 2 n and gates for n input variables and for m outputs from pla there should be m or gates each. I am going to write series of tutorials on fpga modules using spartan 3 fpga module. So the top wire is x2 and the one just below is its negation x2.
Block diagram of pal the inputs of and gates are programmable here.
The pal architecture consists of two main components. So the top wire is x2 and the one just below is its negation x2. In this design the state assignment may be important because the use of a good state assignment can reduce the required number of product terms and hence reduce the required size of the pla.
