1.8.2. Design flow

The Cortex-R7 MPCore processor is delivered as synthesizable RTL. Before it can be used in a product, it must go through the following process:

Implementation

The implementer configures and synthesizes the RTL to produce a hard macrocell. This might include integrating RAMs into the design.

Integration

The integrator connects the implemented design into a SoC. This includes connecting it to a memory system and peripherals.

Programming

This is the last process. The system programmer develops the software required to configure and initialize the processor, and tests the required application software.

Each process:

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 area, maximum frequency, and features of the resulting macrocell.

Configuration inputs

The integrator configures some features of the processor 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 available to the software.

Software configuration

The programmer configures the processor by programming particular values into registers. This affects the behavior of the processor.

Note

This manual refers to implementation-defined features that are applicable to build configuration options. Reference to a feature that is included means that the appropriate build and pin configuration options are selected. Reference to an enabled feature means one that has also been configured by software.
