  • Title: Flow-in-Cloud: a multi-FPGA system for AI application
  • Abstract: Flow-in-Cloud (FiC) is consisting of hundreds of FPGA boards each of which is connected with a power interconnection network. Since each board provides 32 full-duplexed 9.9Gbps serial links, the aggregated bandwidth is up to 316.8Gbps. The STDM (Static Time Division Multiplexing) switching is adopted for emulating future optical switch. Xilinx's cost efficient Kintex Ultrascale is used, and programmers can describe their application modules attached to the switch as HLS modules. Some CNN(Computational Neural Network) application are implemented on a system with 16 boards. HLS modules can be replaced with a dynamic reconfiguration without stopping the switch.

  • Title: New Approaches for Clustering Problems
  • Abstract: Clustering Problem is one of the most fundamental problems in data mining. It partitions the data into several groups, or find groups of entities, so that the entities in a group are similar to each other, or there are sufficiently big gap between two groups. The existing methods are not good at for finding many small clusters or middle sized ones, even though some of them take very long computation time. In this talk, we show the difficulty of this kind of unsupervised problems, and a new approach so called “data polishing” that can find small clusters with high accuracy. We also propose a hierarchical clustering method by meta-clustering of usual k-means algorithms. This kind of approaches would give a new type of HPC to data analysis.

  • Title: A microsystem design using standard CMOS technology with on-chip solar cell
  • Abstract: In this paper, we show the design of the microsystem which autonomously operates only a chip by standard CMOS process. It is intended to operate only with chips created by CMOS process, Use an on-chip solar cell as an energy source. Since the proposed system operates only with chips, bonding and packaging are unnecessary and cost reduction becomes possible. First, we describe a method for improving the efficiency of solar cells fabricated by a standard CMOS process. Next, we will introduce a boost DC-DC converter that operates with the on-chip solar cell as an energy source. The output voltage boosts to 1 V or more at which a general circuit operates. In addition, we show a method to boost to 6 V or more aiming to write on fuse type memory on the chip, and the results of writing to memory are shown. Finally, we will conclude the research progress toward the realization of the microsystem.
