A1.6 Design tasks

The Cortex®‑A32 processor is delivered as a synthesizable Register Transfer Level (RTL) description in the Verilog HDL. Before you can use it, you must implement, integrate, and program it.

A different party can perform each of the following tasks. Each task can include implementation and integration choices that affect the behavior and features of the processor.

The implementer configures and synthesizes the RTL to produce a hard macrocell. This task includes integrating RAMs into the design.
The integrator connects the macrocell into a SoC. This task includes connecting it to a memory system and peripherals.
It is the last task. The system programmer develops the software to configure and initialize the processor and tests the application software.

The operation of the final device depends on the following:

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 configuration settings 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. The configuration choices affect the behavior of the processor.
