• focus: All of the information in this resource is needed for creating systems and

should be read carefully, as familiarity will greatly help students in avoiding time consuming

mistakes.

Nios II is an embedded processor architecture designed specifically for Altera’s FPGA boards.

An example of a Nios II processor system could be found on page 11 from Altera’s Nios II

Processor Reference Handbook. When implementing your board there is three different types

of CPU’s to choose from which are the NIOS II/fast, NIOS II/standard, and NIOS II/economy.

The main differences between the CPU’s are the balance between performance and cost.
