Real-Time Digital Hardware Simulation of the Rodless Pneumatic System

This brief presents an area-efficient hardware implementation for simulating a rodless pneumatic system (RPS) in real time. The proposed implementation involves a very-large-scale-integration architecture. A hardware-sharing technique, which can be used to efficiently reduce the computational resources required, is incorporated into the architecture. Furthermore, the parameters and input/output bit widths are flexible and can be modified for specific applications. To the best of our knowledge, the proposed RPS circuit is the first application-specific integrated circuit (ASIC) implementation, and no related state-of-the-art ASIC design exists in the literature. The simulation indicates that the proposed circuit designed using the Taiwan Semiconductor Manufacturing Company 90-nm technology contains 767-k gate counts and a Q30.24 bit width. The experimental results show that the proposed architecture satisfies precision requirements with low hardware complexity.
