SiFive enhances processor IP portfolio

1 min read

SiFive, a provider of commercial RISC-V processor IP and silicon solutions, has announced a comprehensive update to the company's RISC-V Core IP portfolio with the public availability of the SiFive 20G1 release.

The SiFive Core IP portfolio comprises of a broad range of microarchitectures that scale from high-performance application processors, for running Linux-based applications or real-time deterministic workloads, to low-power microcontrollers focused on efficiency. The IP is developed in partnership with customer requirements that include pre-integrated SiFive Insight, for advanced trace and debug capabilities, and SiFive Shield, for whole-SoC security.

“This release combines our roadmap enhancements with feedback from industry-leading customers to extend our leadership in RISC-V processor IP,” said Dr. Yunsup Lee, co-inventor of RISC-V and CTO of SiFive.

SiFive RISC-V processor cores enable the creation of domain-specific heterogeneous SoCs, based on SiFive U-Series, S-Series, and E-Series Core IP. SiFive U-Series 64-bit processors are Linux-capable and multi-core ready, enabling high-performance core complexes for use in storage, networking, and AI inference processing applications.

In this release, the SiFive U7-Series has increased load bandwidth up to 2.8x for memory-intensive workloads such as AI inference processing. The SiFive 20G1 release also delivers lower power in the entire portfolio, with the SiFive U74 standard core running at up to 25% lower power.

SiFive S-Series 64-bit processors and E-Series 32-bit processors are designed for real-time embedded applications, area-optimised for low power. Combining SiFive’s RISC-V processor cores to create heterogeneous multi-core complexes using domain-specific architectures for AI, aerospace, automotive, IoT, mobile, networking, storage, or vision applications. SiFive E-Series processors are now available with the RISC-V Embedded extension, RV32E, to deliver significant area saving with the SiFive E3-Series measuring up to 11% smaller area than previous versions.

SiFive Core IP seamlessly integrates into mixed-ISA designs with native Arm CoreSight compatibility, enabling developers to leverage their existing software development environment. The suite of SiFive Freedom Tools has been updated to support the SiFive 20G1 release, offering a comprehensive suite of SDKs, compilers, libraries, and code examples to accelerate adoption and use of SiFive RISC-V processor Core IP.

“SiFive’s leadership and talent in RISC-V are demonstrated in the quality and breadth of our products,” said Dr. Naveed Sherwani, Chairman, President & CEO of SiFive. “SiFive’s customers return because of our product portfolio and our great CX team to help develop new products quickly and efficiently.”

The SiFive 20G1 release is now available through the SiFive Core Designer to simplify the selection and configuration of RISC-V cores for domain-specific architecture designs.
