Nios II/f Core
Nios II Processor Reference Handbook
Preliminary support—The core is verified with preliminary
timing models for this device family. The core meets all
functional requirements, but might still be undergoing
timing analysis for the device family. It can be used in
production designs with caution.
Final support—The core is verified with final timing models
for this device family. The core meets all functional and
timing requirements for the device family and can be used in
production designs.

Table 5–3
The Nios II/f fast core is designed for high execution performance. Performance is
gained at the expense of core size. The base Nios II/f core, without the memory
management unit (MMU) or memory protection unit (MPU), is approximately 25%
larger than the Nios II/s core. Altera designed the Nios II/f core with the following
design goals in mind:
■
■
■
The resulting core is optimal for performance-critical applications, as well as for
applications with large amounts of code and/or data, such as systems running a
full-featured operating system.
