Connecting bridge in SoC used for wireless home healthcare system

A connection bridge for connection of two CPU systems in SoC of the HAB (healthcare apparatus on body/bed) in home healthcare wireless network is addressed. Multi CPU system in a SoC could be divided into different part according with data process function. Therefore the each part of the system can work independently without influence each other. With the discussion of the performance of HAB and home networking, the connection bridge is a suitable technology for reducing dies size and power consumption. The connection bridge designed in the paper connects two CPU systems and two digital circuitry components together. To the CPU system, common digital circuitry is a part of the CPU system with the bridge. The architecture and logic function of the connection 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, display module and RAM, but also increase the running speed and system performance.
