| Research Abstract |
In addition to high speed data processing by supercomputing, introducing of the functions of the human brain has contributed to build flexible computers. Structural hints from the human brain allowed us to think about more flexible functions that lead to various data/information processing. In this research we have improved the architecture of brain-structured computers, designed an MISD processor, and implemented an example of the design. We call this architecture the SHIFT MACHINE architecture which can be regarded as an MISD computer. This work is based upon several research results consisting of the analysis of VLIW architectures with a cache analysis and a speculation method. The simulator of the SHIFT MACHINE is available to show its behavior visually. Related to the SHIFT MACHINE architecture, we have also developed a reconfigurable synchronous dataflow computer called SOUND. This was implemented in a chip processor fashion and evaluated. As a result, the left-brain function has

been implemented and the speed has been accepted to be a suitable one under low power condition. On the other hand, the right brain has been implemented in the research of computer graphics and volume rendering. These two subjects has been realized speedy and flexibly by improving the algorithms. In computer graphics of our system, the algorithm is evaluated on a commercially available parallel machine and we got the fast rendering. This fact is proved in volume rendering. Developing reasonable algorithms for computer graphics and volume rendering, we can reach some potential to show fast rendering that is suited for real time processing and rendering. Further neural network research has been developed to discover the right brain function. The results are worth comparing artificial mechanism with the human brain structure.
From these two results in left-brain and right brain research, we have discussed the integration of these two brain functions in terms of the mutual behavior of the functions of the left and right brains. To have these two get together, we concluded that the integration is based on the processing speed on computers engaged in the left and right brains. To increase their processing speed, we have developed the architecture with software including special speculation. Also a cache mechanism has been developed to have high speed processing. Less
