The application processors offer best in class performance, area and efficiency for a wide variety of AI & ML markets

Bringing maximum throughput while preserving efficiency of AI & ML workloads, here are two new SiFive Performance family processors, the P270, a Linux capable processor with full support for the RISC-V vector extension v1.0 rc and the P550 core that delivers a SPECInt 2006 score of 8.65/GHz.

The P270 is an 8-stage, dual-issue, highly efficient in-order pipeline compatible with the RISC-V RV64GCV ISA. With full support for the RISC-V Vector Extension v 1.0RC, and combined with SiFive Recode, which translates existing SIMD software from popular legacy architectures to RISC-V Vector assembly code, the P270 is an ideal replacement for dated SIMD architectures.

The P550 features a thirteen-stage, triple-issue, out-of-order pipeline compatible with the RISC-V RV64GC ISA. Evolved from the previously announced SiFive U84 microarchitecture, P550 scales up to four-core complex configurations that use a similar amount of area as a single Arm Cortex-A75 while delivering a significant performance-per-area advantage.

“These two new products cover new performance points and a wide range of application areas, from efficient vector processors that easily displace yesterday’s SIMD architectures, to the bleeding edge that the P550 represents,” said Dr Yunsup Lee, Co-Founder and CTO of SiFive.

“By combining Intel’s leading-edge interface IP such as DDR and PCIe with SiFive’s highest performance processor, Horse Creek will provide a valuable and expandable development vehicle for cutting-edge RISC-V applications,” said Amber Huffman, Intel Fellow and CTO of IP engineering group at Intel.

“Combined with the maturing and growing open-source software ecosystem for RISC-V developed by leading technology industry companies, chip designers have a real choice for their next SoC application processor core,” said Kevin Krewell, Principal Analyst, TIRIAS Research.

The new SiFive Performance family joins the SiFive Essential family of configurable cores that includes the U/S/E-Series of 64-bit and 32-bit processors.
