Abstract
Programmable high speed state machines with sequencing capabilities based on a dual array structure with state information and fast sequencing logic placed between the two arrays are disclosed. The state section consists of multiple registered macrocells which are connected to function as program counters and decoders to the output array. The input array has feedback from the state registers and input from the dedicated inputs and input/output pins around the device. The inputs of the input array are all individually configurable as registered or nonregistered, with the inputs being divided into three groups, input/output, Mealy and simple inputs, with three enable product terms from the output array controlling the respective groups. Various additional characteristics, features and capabilities of the invention are disclosed.
