Recently, RISC-V International announced the approval of the first four specifications and extensions in 2022, including RISC-V Efficient Tracking (E-Trace), RISC-V Supervisory Binary Interface (SBI ), RISC-V Unified Extensible Firmware Interface (UEFI) specification, and RISC-V Zmmul pure multiplication extension. Among them, E-Trace will accelerate the design of large-scale chip systems based on RISC-V, which not […]

Axiomise Axiomatizes RISC-V Processors Through Formal Verification
Although it is economically feasible to design new microprocessors due to open-source architectures, testing and verification remain major hurdles. With the emergence of open source processor architectures such as RISC-V, chip design has become more and more democratized, and more and more organizations dare to dabble in processor design, from embedded microcontrollers to high-end desktop […]
The RISC-V architecture spreads good news in the field of data centers
Electronic Enthusiast Network (text/Wu Zipeng) Previously, “Queen of the Bull Market” Catherine Wood mentioned in her 2021 technology trend release that the Intel era will end, and ARM, RISC-V and GPU will become mainstream processors.In her prediction, the X86 architecture, which currently accounts for nearly 100% of the data center field, will decline in the […]
Unwilling to be surpassed by China, the United States and Japan, the European Union finally invests in HPC
When it comes to supercomputers, most people think of Fujigake in Japan, Summit in the United States, and Sunway TaihuLight in China, but rarely think of the European market. In fact, there are 113 supercomputing systems from Europe in the TOP500, but only two can be ranked in the top ten. Germany’s JUWELS and Italy’s […]
What does the new specification approved for RISC-V mean?
On December 2, US time, the RISC-V International Foundation announced that its members had approved 15 new specifications, including more than 40 extensions under the RISC-V instruction set architecture, with emphasis on its vector, scalar encryption and Hypervisor Three rules. The RISC-V International Foundation stated that these specifications have created new opportunities for markets such […]
RISC-V architecture handles exceptions in machine mode
Last time we talked about processor interrupts and exceptions, we just overlooked this function from high to low. Did not fall to the real point, not specific to the details. There is a problem in the last chapter. Let me correct it here. The narrow-sense interruption and the narrow-sense exception together constitute a generalized exception […]
How to think about custom extended instruction set architecture in RISC-V SoC design
Talk of configuring the base processor or adding custom extensions to address hardware-software design tradeoffs in a system-on-chip (SoC) is nothing new. This has been a key part of the value proposition supported by the RISC-V community, with many publications and benefits such as “A Guide to Accelerating Applications Using Just the Right RISC-V Custom […]
Yuefang Technology: Launched NB2, a RISC-V architecture application processor for smart transportation-RSU
(Text/Cheng Wenzhi) At the 12th Songshan Lake China IC Innovation Summit Forum on August 5th, at the promotion meeting of innovative IC new products for “smart travel”, Yuefang Technology Co., Ltd. brought its smart transportation-RSU NB2, a high-end application processor with RISC-V architecture of Full Mask, has been successfully taped out in the fourth quarter […]
Open source RISC-V architecture changes the game for IoT processors
Open source software has been one of the biggest catalysts in the tech world over the past decade. Today, the power of open source, the freedom it brings, and the community it engenders is also gaining traction in the hardware world. For these reasons, RISC-V is gaining popularity. This is an introduction to RISC-V and […]
Open computing using RISC-V and memory fabrics
Over the past few years, we have witnessed dramatic changes in the way data is generated, processed, and further exploited for additional value and intelligence, all influenced by the emergence of new computational models based on deep learning and neural network applications. This profound change begins in the data center, where deep learning techniques are […]
