摘要：The multi-layer advanced high-performance bus (ML-AHB) BusMatrix proposed by ARM is an excellent architecture for applying embedded systems with low power. However, there is one clock cycle delay for each master in the ML-AHB BusMatrix of the advanced microcontroller bus architecture (AMBA) design kit (ADK) whenever a master starts new transactions or changes the slave layers. In this letter, we propose an improved design method to remove the one clock cycle delay in the ML-AHB BusMatrix of an ADK. We also remarkably reduce the total area and power consumption of the ML-AHB BusMatrix of an ADK with the elimination of the heavy input stages.
