It is claimed that Al applications have moved from laboratories to the real world. However, conventional von Neumann computers are (66) for Al applications, because they are de- signed mainly for numerical processing. In a larger yon Neumann computer, there is a larger ratio of memory to processing power and consequently it is even less efficient. This (67) remains no matter how fast we make the processor because the length of the computation becomes dominated by the time required to move data between (68) and memory. This is called the yon Neumann (69) . The bigger we build the machines, the worse it gets. The way to solve the problem is to diverse from the traditional architectures and to design special ones for Al applications. In the research of future Al architectures, we can take advantages of many (70) or currently emerging concepts. in computer architecture, such as dataflow computation, stack machines, tagging, pipelining, systolic array, multiprocessing, distributed processing, database machines, and inference machines.
