Abstract
A heterogeneous programmable gate array has an unstructured logic sub-array and a structured logic sub-array. An unstructured input/output interconnect structure delivers unstructured-to-unstructured input/output signals to the unstructured logic sub-array, while a bussed input/output interconnect structure delivers structured-to-structured input/output signals to the structured logic sub-array. A control signal bus is connected between the unstructured logic sub-array and the structured logic sub-array to deliver unstructured source signals therebetween. A bussed signal bus is connected between the unstructured logic sub-array and the structured logic sub-array to deliver structured source signals therebetween.
