4. Instantiating the Nios II
Processor in SOPC Builder
Introduction
This chapter describes the Nios
®
II Processor MegaWizard interface in
SOPC Builder. This chapter contains the following sections:
■ “Core Nios II Page” on page 4–2
■ “Caches and Memory Interfaces Page” on page 4–6
■ “Advanced Features Page” on page 4–9
■ “JTAG Debug Module Page” on page 4–10
■ “Custom Instructions Page” on page 4–14
The Nios II Processor MegaWizard interface allows you to specify the
processor features for a particular Nios II hardware system. This chapter
covers only the features of the Nios II processor that you can configure
with the Nios II Processor MegaWizard. It is not a user guide for creating
complete Nios II processor systems.
f To get started using SOPC Builder to design custom Nios II systems,
refer to the Nios II Hardware Development Tutorial. Nios II development
kits also provide a number of ready-made example hardware designs
that demonstrate several different configurations of the Nios II
processor.
The Nios II Processor MegaWizard interface has several pages. The
following sections describe the settings available on each page.
1 Due to evolution and improvement of the Nios II Processor
MegaWizard interface, the figures in this chapter might not
match the exact screens that appear in SOPC Builder.
