Switch Bridge Architecture of NoC for Wireless ECG Data Acquisition

A switch bridge is addressed for the interconnection of two CPU systems in the SoC of the ETB (ECG terminal on body) in home healthcare wireless network. The SoC including multi CPU systems can be divided into different parts with data process function. Therefore each part of the system can work independently without influence each other. With the discussion of the performances of HAB and home networking, the switch bridge is a suitable technology for reducing the dies size and power consumption. The switch bridge designed in this paper connects two CPU systems and two others digital circuitry components together. To the CPU systems, common digital circuitry is a part of the CPU system with the bridge. The architecture and logic function of the switch bridge is analyzed in detail and simulated. The simulation results demonstrate that the connection bridge can not only supply the connection of two CPU and two common components, include display module and RAM, but also increased the running speed and system performance.
