1.1. About the AHB MC

The AHB MC is an Advanced Microcontroller Bus Architecture (AMBA) compliant System-on-Chip (SoC) peripheral. It is developed, tested, and licensed by ARM Limited.

The AHB MC takes advantage of the newly developed Dynamic Memory Controller (DMC) and Static Memory Controller (SMC). The AHB MC has six AHB ports with access to the external memory. Each AHB port has a bridge interface to the memory controllers. There is a separate AHB port to configure the memory controllers. Specific configurations of the SMC and DMC are instantiated to target specific memory devices. Figure 1.1 shows the AHB MC (PL244) configuration.
