Abstract
A programmable logic array integrated circuit has a number of relatively simple logic modules which can be interconnected in any of a wide variety of ways via a general purpose interconnection network to enable the circuit to perform logic functions which can be quite complex. In addition, at least some of the logic modules are connectable to one another by cascade connections and include additional logic elements for logically combining the outputs of the cascade connected modules so that modules can be concatenated to perform relatively complex logic functions without always having to make use of the general purpose interconnection network.
