Abstract
FPGAs and MPLDs, which are conventional programmable semiconductor devices, have had poor cost performance and did not suitably take long signal lines into account. To solve this, a flip-flop is built into each MLUT block comprised of a plurality of MLUTs, each MLUT comprising a memory and an address-data pair. With respect to the adjacent line between adjacent MLUTs, alternated adjacent line are introduced, while in the case of interconnects between non-adjacent MLUTs, dedicated distant line and, furthermore, a torus interconnect network are provided.
Claims20
A semiconductor device characterized by comprising a basic unit being a MLUT block constituted by N number (N is an integer of 1 or greater) of MLUTs each having a memory and I/O signal wires that are address wires and data wires arranged/wired in pairs;
- wherein the MLUTs are interconnected by the address-data pairs, and a plurality of the basic units, or MLUT blocks, are arranged and a flip-flop is provided for the MLUT block.
