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 Static Memory Controller
(SMC). The AHB MC has an AHB port with access to the external memory. The AHB
port has a bridge interface to the memory controller. There is a separate AHB port to
configure the memory controller. Specific configurations of the SMC are instantiated to
target specific memory devices. Figure 1-1 shows the AHB MC (PL241) configuration.
