Andes Technology Launches RISC-V FreeStart Program with its Commercial-Grade CPU N22


AndesCore™ RISC-V CPU IP N22 integrated with interrupt controller, local memory, instruction cache, debug support, and an optional AHB platform


HSINCHU, TAIWAN June 10, 2019 – Andes Technology Corporation, a leading supplier of high performance, low-power, compact 32/64-bit CPU cores embedded in over 1 billion SoC in 2018 alone, today announces its RISC-V FreeStart program. The program offers an easy and fast way to build a solid SoC foundation on the commercial-grade RISC-V CPU core N22, available for free download. AndesCore™ N22 is an entry-level, ultra-compact, low-power and performance-efficient RISC-V CPU IP. It delivers the highest 3.95 Coremark/MHz in its class, and offers rich configurable features, including multiplier, interrupt controller, local memory, instruction cache, debug support, and an optional AHB platform. With the RISC-V FreeStart program, SoC engineers can begin designing a RISC-V based SoC without budgeting CPU IP upfront.

“RISC-V is finding rapid adoption and creating high demand, especially in MCU level applications,” said Andes Technology President, Frankwell Jyh-Ming Lin. “Designers are seeking a small, efficient, and yet high performance-efficient commercial RISC-V core to construct their creative SoCs. Unlike open source RISC-V CPUs which are with limited features and lack of documents, and need to be verified by SoC designers first, users of the commercial-grade N22 can skip this time-consuming task which adds nothing to the value of their final SoC and instead spend their precious design resources on their true value added.”

“The N22 CPU is a small, 2-stage pipeline 32-bit RV32I/EMAC RISC-V CPU core, 16 or 32 general purpose registers, multiplier, atomic and compressed instructions. It also supports several unique and configurable features such as StackSafe™ for hardware stack protection, PowerBrake for efficient power management, CoDense™ for code size reduction on top of RISC-V C extension, and local memory and instruction cache for performance boost,” stated Andes CTO and Executive Vice President, Dr. Charlie Hong-Men Su. “The program also provides designers the option of 1-year support and a pre-integrated AHB platform with commonly used peripheral IPs, thus saving the time of sourcing and integrating these into their design. In addition, the RISC-V FreeStart can leverage the AndeSight™ IDE, a professional software development environment with over 15,000 worldwide installations, which has been available for free download.”


The RISC-V FreeStart program has been launched now. Anyone from industrial professionals to school students is invited to view and sign the online license agreement and download the N22 processor for evaluation purpose. The FreeStart also provides mass production program that allows industry, research institutes and academia to make commercial chips with running royalty or for research purpose but allow path of migration to mass production. Design teams can choose the optional technical support program available through Andes online e-service, which comes with an AHB platform RTL code for SoC integration.
