Bridge for Connecting Two CPU Systems in a SoC

Abstract

The connection bridge is addressed for connecting different circuit part include two CPU system in a SoC. With the discussion about the performance of circuitry components, the circuitry components are classified into two types, one is called host transmission component, and the other is called slave transmission component. The classification is the fundamental for connection bridge design. By this classification, a connection bridge was designed in this paper. The connection bridge designed in the paper connect two CPU system and three others digital circuitry components together and make the CPU connected with three digital circuitry directly as a part of the CPU system. 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 three common components, include RAM, ADC and DAC, but also increased the running speed and system performance.
