SoC Architecture with a Switch Bridge for Wireless ECG Data Acquisition

NoC architecture with a switch bridge is designed for mixed signal SoC of the ETB (ECG T on body) applied 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 ETB, the switch bridge is a suitable NoC (network on chip) 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 cannot only supply the connection of two CPU and two common modules, include display module and RAM, but also increased the running speed and system performance.
