Area Optimization of Slicing Floorplans in Parallel
We first present a parallel algorithm for finding the optimal implementations for the modules of a slicing floorplan that respects a given slicing tree. The algorithm runs in O(n) time and requires O(n) processors, where n is the number of modules. It is based on a new O(n2) sequential algorithm for solving the above problem. We then present a parallel algorithm for finding a set of optimal implementations for a slicing floorplan whose corresponding slicing tree has height O(logn). This algorithm runs in O(n) time using O(logn) processors. Our parallel algorithms do not need shared memory and can be implemented in a distributed system.
