A VLSI-based intelligent peripheral for a marine simulator computer system

The author presents a new design strategy for the artificial reproduction of ship-board-generated sounds for temporal marine simulators. An overview is furnished of previous analog and digital synthesis techniques. A coherent design rationale for a VLSI-based digital sound synthesizer prototype is discussed, together with a full description of the interface bus, which permits very fast communications with the main simulator computer. A flow chart of the sound synthesizer board and a circuit diagram of its VLSI realization are provided.<
