Customer Case: Andes N22 Ultra-Low Power RISC-V Processor
Andes Technology Corporation is a leading embedded microprocessor intellectual property supplier based in Taiwan.
Nuclei co-worked with Andes on N22, their ultra compact 32-bit RISC CPU core in 2018 when Nuclei was ust founded.
Nuclei completed the hardware design implementation and partial of function verification. It was a win-win
collaboration for both Andes and Nuclei.
