RISC-V Announces First New Specifications of 2022, Adding to 16 Ratified in 2021

Jun. 21, 2022 – 

Efficient Trace, Supervisor Binary Interface, Unified Extensible Firmware Interface, and Zmmul Multiply-Only Extension Accelerate Embedded- and Large-System Design.

Nuremberg, Germany – June 21, 2022RISC-V International, the global open-design standards pioneer, announced its first four specification and extension approvals of 2022 – Efficient Trace for RISC-V (E-Trace), RISC-V Supervisor Binary Interface (SBI), RISC-V Unified Extensible Firmware Interface (UEFI) specifications, and the RISC-V Zmmul multiply-only extension. The news builds on momentum from 2021, in which 16 specifications representing more than 40 extensions were ratified.

“The RISC-V culture of contribution and collaboration continues to produce impressive and strategic results,” said Calista Redmond, CEO of RISC-V. “RISC-V members are leaders in the era of open compute, proving that collaboration accelerates innovation through shared investment while growing global opportunity.”

“These new specifications accelerate embedded and large-system design,” said Mark Himelstein, CTO of RISC-V. “Debugging is one of the hardest things to do on a chip,” he explained. “E-Trace for RISC-V creates a standard way to do processor trace that’s extremely efficient and is especially useful in embedded system design.”

“RISC-V SBI offers developers a similarly critical resource,” Himelstein added. “The ability to port supervisor-mode software across all RISC-V implementations, essentially allowing developers to write something once and apply it everywhere.”

“UEFI is a critical element of any system,” said Himelstein, “In some applications, it may replace basic BIOS software.”



RISC-V IP Cores

“For many microcontroller applications, division operations are too infrequent to justify the cost of divider hardware,” explained Himelstein. “The RISC-V Zmmul extension will benefit simple FPGA soft cores in particular.”

RISC-V announced the ratifications at Embedded World here, where RISC-V is the focus of several talks. RISC-V International is also hosting a pavilion of member-company innovations in the exhibition hall through June 23rd. Showcase participants include Andes Technology; CAES, Cobham Gaisler; Canonical Ubuntu; Codasip; Codeplay; Digital Core Technologies; GreenWave Technologies; Imperas; OpenHW Group; SiFive; Syntacore and Ventana Micro Systems.

About RISC-V International

RISC-V International is the non-profit home of the open standard RISC-V Instruction Set Architecture (ISA), related specifications, and stakeholder community. More than 2,800 RISC-V members across 70 countries contribute and collaborate to define RISC-V open specifications as well as convene and govern related technical, industry, domain, and special interest groups. RISC-V combines a modular technical approach with an open, royalty-free license model — meaning that anyone, anywhere can benefit from the IP contributed and produced by RISC-V. RISC-V enables the community to share technical investment, contribute to the strategic future, create more rapidly, enjoy unprecedented design freedom, and substantially reduce the cost of innovation.
