Design flow

The MMU-600 is delivered as synthesizable RTL. Before it can be used in a product, it must go through the following processes:

Implementation
The implementer configures and synthesizes the RTL to produce a hard macrocell. This process might include integrating RAMs into the design.
Integration
The integrator connects the implemented design into a SoC. Integration includes connecting the design to a memory system and peripherals.
Programming
The system programmer develops the software to configure and initialize the MMU-600, and tests the required application software.

Each process is separate, and can include implementation and integration choices that affect the behavior and features of the MMU-600.

The operation of the final device depends on:

Build configuration
The implementer chooses the options that affect how the RTL source files are pre-processed. These options usually include or exclude logic that affects one or more of the following:
  • Area.
  • Maximum frequency.
  • Features of the resulting macrocell.
Configuration inputs
The integrator configures some features of the MMU-600 by tying inputs to specific values. These configurations affect the start-up behavior before any software configuration is made. They can also limit the options that are available to the software, for example, by enabling QoS features.
Software configuration
The programmer configures the MMU-600 by programming particular values into registers. This configuration affects the behavior of the MMU-600.
