ABSTRACT:
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 programmably-configured interconnections.
