Extend IOP16 minimal example

Overview

• This is a guide to extending the minimal IOP example by adding IOP16 Peripherals to the minimal design
• This is not the same as Embedding the IOP16 into another design
• This guide requires general familiarity with IOP16 16-bit I/O CPU Design

Sources

• Build requires two GitHub repositories
  • Clone the two repositories to the same directory level since relative paths are used for source files
    • IOP16 GitHub repository
    • Design a CPU GitHub repository
• Start by building the minimal example
  • Adjust I/O pins as required for the FPGA that is being used
    • This example does not cover porting to another FPGA card

Steps

• Copy baseline design
• Select/add peripherals
• Create new peripherals
• Write assembly code

Baseline Design

• Starts from IOP example
  • Similar to Arduino "Blink Sketch" and uses the resources
    • Timer Unit 0 1 second timer
    • On-board LED
  • The Timer unit could be removed if desired
    • Timer makes Blink easier
• Copy the minimal design to a new folder
