4.1.1. Core Selection

The main purpose of the Core Nios II tab is to select the processor core. The core you select on this tab affects other options available on this and other tabs.

Altera offers the following Nios II cores:

  • Nios II/f—The Nios II/f fast core is designed for fast performance. As a result, this core presents the most configuration options allowing you to fine tune the processor for performance.
  • Nios II/s—The Nios II/s standard core is designed for small size while maintaining performance.
  • Nios II/e—The Nios II/e economy core is designed to achieve the smallest possible core size. As a result, this core has a limited feature set, and many settings are not available when the Nios II/e core is selected.

The Core Nios II tab displays a selector guide table that lists the basic properties of each core.

For implementation information about each core, refer to the Nios II Core Implementation Details chapter of the Nios II Processor Reference Handbook.
