A COMBINING TECHNIQUE OF RATE LAW FUNCTIONS FOR A COST-EFFECTIVE RECONFIGURABLE BIOLOGICAL SIMULATOR

In order to simulate large scale biological models with a reconfigurable FPGA-based biochemical simulator system, reduction of required resources are essential. This paper proposes a method which combines common terms in rate law functions appeared in biochemical models and generates a shared hardware module used for numerical integration. In this approach, two functions are combined in a tree structure level, followed by pipeline scheduling and arithmetic module binding. The evaluation result reveals that this approach reduces hardware resources by 31.4 % on average at the cost of 14.4 % throughput degradation.2007 International Conference on Field Programmable Logic and Applications : Amsterdam, Netherlands, 2007.08.27-2007.08.2
