Temporal Graph Placement on Mesh-Based Coarse Grain Reconfigurable Systems Using the Spectral Method

Coarse grain architectures need domain specific place and route methods. The existence of such methods provided, algorithms can be executed in time and space on the processing elements of coarse grain reconfigurable systems. Additionally, the short reconfiguration time and reduced power requirements comparing to FPGA makes coarse grain systems worth to be scrutinized as alternative execution platforms. By help of spectral methods, which target quadratic distance optimization of graphs, we can achieve short communication distances. This paper shows how to use the spectral method for efficiently scheduling processing elements of coarse grain reconfigurable devices by combining the spectral method and ASAP scheduling.
