Andes Technology's N25F RISC-V Processor Enables Superior Performance And Low Power For Phison's X1 Enterprise SSD Controller

HSINCHU, TAIWAN – April 25, 2023 – Andes Technology (TWSE: 6533; SIN: US03420C2089; ISIN: US03420C1099), a leading supplier of high-efficiency, low-power 32/64-bit RISC-V processor cores and Founding Premier member of RISC-V International, and Phison Electronics Corp. (TPEX: 8299), a global leader in NAND flash controller and storage solutions, today announces that the AndesCore™ N25F Processor has been adopted by Phison’s award-winning PCIe Gen4x4 SSD Controller X1 (PS5020-E20) for the enterprise SSD market. The fast and compact N25F provides good balance between performance, area and power, which has made it widely adopted in SoCs demanding performance-efficient embedded controllers.

The AndesCore™ N25F is a 32-bit CPU IP core based on the AndeStar™ V5 architecture, which extends but is compatible to the RISC-V architecture. With an optimized 5-stage pipeline design, it can deliver the leading per-MHz performance with excellent energy efficiency. The N25F also has comprehensive options for its memory subsystem, including instruction and data caches, local memories with low-latency and predictable accesses, and ECC for L1 memory soft error protection. To support flexible SoC construct, the N25F system bus can be configured as 64-bit AXI, 64-bit AHB, or 32-bit AHB, and there is also a slave port for direct local memory reads/writes. These capabilities ensure both speed and security in memory accesses. In addition, the Andes Customer Extension™ (ACE) framework offers additional flexibility through customized special purpose instructions. With rich features and customized options, the N25F has been very popular in the embedded controller market.

The Phison X1 SSD platform, an U.3 PCIe 4.0 x4 NVMe SSD, is a product targeting the enterprise SSD market. Its great boost in random read IOPS is a crucial evidence for its suitability in AI training and application servers handling thousands of clients. The X1 platform offers higher speed with lower energy consumption in a cost-effective solution that eliminates performance bottlenecks, significantly improves quality of service (QoS), and delivers the highest levels of data integrity and security for critical business applications. It was also recently awarded the 2023 Taiwan Excellence Award.

“Phison has been working with Andes for almost a decade, from the previous V3 architecture to the RISC-V based V5 architecture. All AndesCore™ processors offer an extensive list of configurable options, and the ACE automation tool is very powerful in creating customized instructions that fits our exact needs.” Vincent Cheng, VP of R&D of Phison said. ” We are happy to be working with Andes. Through the processor and technical support provided by Andes, it is believed that the two companies will have more possibilities for cooperation in the future.”

“The AndesCore™ N25F offers efficient performance and flexible configuration, which makes it the perfect choice for performant embedded controllers. Actually, the N25F has been the best-selling RISC-V core.” said Andes CTO and President Dr. Charlie Su. “We are grateful to work with Phison on many projects. Phison is an ideal customer who continues to develop successful products with Andes processors while providing useful feedbacks on our cores and development tools along the way. We have extended our collaboration to the superscalar D45 core and we expect more successful products from Phison based on AndesCore™.”
