Standard Nios II Hardware Design Example
The standard Nios® II hardware design example is based on the Nios II /s processor core and provides a mix of peripherals and memories similar to a typical Nios II processor system. The SOPC Builder system automatically generates an interface to each hardware component on the Nios II development board, such as SDRAM, LEDs, an RS-232 connector, and an Ethernet MAC/PHY.
The standard design can be used as a starting point for your own embedded system by adding or removing components to meet your custom requirements. This design is provided for all Altera® Nios II development kits.
