A Multiprocess Network Logic with Temporal and Spatial Modalities. Revised.

摘要

We introduce a modal logic which can be used to formally reason about synchronous fixed connection multiprocess networks such as VLSI. Our logic has both temporal and spatial modal operators. The various temporal modal operators allow us to relate properties of the current state of a given process with properties of succeeding states of the given process. Also, the spatial modal operators allow us to relate properties of the current state of a given process with properties of the current state of neighboring processes. Many interesting properties for multiprocessor networks can be elegantly expressed in our logic. We give examples of the diverse applications of our logic to packet routing firing squad problems, and systolic algorithms. (Author)
