Cortex-M System Design Kit

Example Systems

The CMSDK provides example AMBA systems to bring the designer to a point of a working system as quickly as possible, offering a library of fundamental peripherals and interconnect generation along with software drivers and examples:

Figure 1: ARM Cortex-M0 Example System

The example system supports a number of configuration options. For example:

• DMA option – if the ARM CoreLink™ DMA-230 DMA controller is licensed you can plug in the DMA controller and use it in the system immediately. You can also modify the design to use your own DMA controller.
• Bit band wrapper – if the system requires bit band compatibility with Cortex-M3 or Cortex-M4 this functionality can be included.
• Boot ROM – this option demonstrates how to design a system with boot loader ROM in addition to the user program memory (for example flash).

It is straightforward to extend the example system and plug in other peripheral designs. For designers new to AMBA the example AHB and APB slaves are a good starting point for your design.

An example system for Cortex-M3 and Cortex-M4 processors is also included, as the figure below shows:

Figure 2: ARM Cortex-M3/4 Example System

The Cortex-M3, Cortex-M4 system has the same memory map and interrupt assignments as the Cortex-M0 system. It also uses the same AMBA APB subsystem as the Cortex-M0 example. Again, the integration of the DMA controller and boot loader is optional.
