Nios II is a 32-bit embedded processor architecture designed specifically for the Altera family of field-programmable gate array (FPGA) integrated circuits. Nios II incorporates many enhancements over the original Nios architecture, making it more suitable for a wider range of embedded computing applications, from digital signal processing (DSP) to system-control.
Nios II is a successor to Altera's first configurable 16-bit embedded processor Nios, introduced in 2000.
Intel announced the discontinuation of Nios II in 2023, with its successor being Nios V, based on the RISC-V architecture.
