Using the Nios II hardware reference designs included in an Altera development kit,
you can prototype an application running on a board before building a custom
hardware platform.
design available in an Altera Nios II development kit.
If the prototype system adequately meets design requirements using an
Altera-provided reference design, you can copy the reference design and use it as is in
the final hardware platform. Otherwise, you can customize the Nios II processor
system until it meets cost or performance requirements.
In practice, most FPGA designs implement some extra logic in addition to the
processor system. Altera FPGAs provide flexibility to add features and enhance
performance of the Nios II processor system. Conversely, you can eliminate
unnecessary processor features and peripherals to fit the design in a smaller,
lower-cost device.
Because the pins and logic resources in Altera devices are programmable, many
customizations are possible:
■
You can rearrange the pins on the chip to simplify the board design. For example,
you can move address and data pins for external SDRAM memory to any side of
the chip to shorten board traces.
