Research Abstract |
Real-world applications need to achieve very quick response for dynamically changing real-world environment. Therefore, it is very important to develop a "Super Chip for Intelligent Integrated Systems." The emerging technologies of intelligent integrated systems for real-world applications rely increasingly on VLSI processors high degree of parallelism in various levels such as architectural, logic design, and circuit/device level. The following items are the themes discussed in this project : (1)Discussion about algorithm/system/architecture-level innovation : We have discussed about the efficiency of multiple-valued logic-in-memory VLSI as the development of fully parallel image processor for intelligent integrated systems. The basic idea of the multiple-valued logic-in-memory VLSI architecture is that the data which are frequently used in the communication between the processing element (PE) and the memory are stored into the local memory tightly connected to the PE.We also discussed about the efficiency of some concrete examples using such concept. (2)Discussion about logic-design/circuit-design-level innovation : We have presented a floating-gate-MOS pass-transistor network as a circuit-level logic-in-memory VLSI architecture. We have discussed about the usefulness of such a new pass-transistor network and about its application areas. While a floating-gate MOS transistor is used as a multiple-valued storage element in the present VLSI system, some logical functions such as a threshold function and a pass-switch function are merged into the multiple-valued memory plane. (3)Discussion about device/process-technology-level innovation : We have also discussed about the device technologies to realize the floating-gate-MOS pass-transistor network.
