Fujimoto, Richard M. | Systolic array synthesis by static analysis of program dependencies | We present a technique for mapping recurrence equations to systolic arrays. While this problem has been studied in fairly great detail, the recurrence equations that are analysed here are a generalization of those studied previously. In a n earlier paper (14] we have showed how systolic arrays can b... | Systolic array synthesis; static analysis; program dependencies; recurrence equations | 1986 |

Fujimoto, Richard M. | Optimal performance of distributed simulation programs | This paper describes a technique to analyze the potential speedup of distributed simulation programs. A distributed simulation strategy is proposed which minimizes execution time through the use of an oracle to control the simulation. Because the strategy relies on an oracle, it cannot be used for ... | Distributed simulation programs | 1987 |

Thomas, Spencer W. | Set operations on sculptured solids | A general method is presented for performing Boolean set operations on solids represented by a sculptured surface boundary model. The method is developed first for solids with closed boundary surfaces. It is then shown to apply also to "partially bounded" solids, which have incompletely specified b... | Set operations; Sculptured solids; Sculptured surface; Boundary model | 1987 |
