A heterogeneous integrated circuit device comprising a field programmable gate array (FPGA) programmably connected to a mask-defined application specific logic area (ASLA) on an integrated circuit thus providing a flexible low cost alternative to a homogeneous device of one type or the other. By integrating both on a single monolithic IC, the user benefits from both low cost and flexibility. Routing of signals between gate arrays and between the gate arrays and input/output (I/O) circuits is also implemented as a combination of mask-defined and programma...
[ What is claimed is:] [1.] A monolithic integrated circuit comprising:an array of field programmable gates selectively interconnected by programmable switch matrices, said gates and said switch matrices being selectively programmable after manufacture in accordance with desired gate functions and connection relationships;an array of mask-defined gates having permanent customized functions and connection relationships;a plurality of externally accessible signal connections coupled to said arrays of programmable gates and mask-defined gates, said external...
