  • Patent number: 8283945
    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.

  • Patent number: 7178008
    Abstract: A parallel processor has a plurality of operation units that execute operation instructions, and a multi-bank register file in which a plurality of banks each having a plurality of registers are formed. Each of machine instructions, which are input simultaneously, is split into a plurality of nano-instructions each of which includes at least one of an access instruction and operation instruction. The output clock cycles of operation instructions with respect to the operation units are arbitrated. Furthermore, the output clock cycles of access instructions to the multi-bank register file are arbitrated so as to prevent access instructions from contending in an identical bank in the multi-bank register file.

  • Patent number: 7117291
    Abstract: In a synchronous multi-port bank memory, registers/buffers receive a read/write signal and an address signal from each of external ports, receive and send a data signal to and from each of the external ports, and receive and send a port block signal. An access conflict management circuit receives the address signals from the registers and buffers and generates the port block signal when an access conflict to the bank occurs. A switching network receives the read/write signal and the address signal from the registers/buffers and generates a bank selection signal when no port block signal is received, so as to activate the selected bank. Thus, memory access cycle time is shortened. A synchronous 1-port bank memory is also constructed similarly.
