Today, a friend in the group felt that the development of RISC-V is slow? This person probably doesn’t understand the history, so let’s first talk about the concept of RISC, which has actually been proposed a long time ago. Back then, Patterson and his team at Berkeley introduced the RISC concept, which essentially aims to … Read more
(Source: riscv)The unstoppable rise of Artificial Intelligence (AI) across various industries is driven by multiple symbiotic factors. On a technical level, the explosion of usable data generated by digital and interconnected processes lays a solid foundation for AI training and inference. Meanwhile, advancements in processor and accelerator hardware, coupled with the proliferation of AI-ready software … Read more
On August 13, at the biennial National Computer Architecture Academic Conference (ACA2020), Hu Weiwu, Chairman of Loongson Technology and researcher at the Institute of Computing Technology, Chinese Academy of Sciences, delivered a keynote report titled “Autonomy and Compatibility of Instruction Systems”. In the report, he revealed new developments from Loongson—the development of the LoongArch instruction … Read more
Click the above blue text to follow us ARM, MIPS, and RISC-V are three common Reduced Instruction Set Computing (RISC) architectures, each with its own characteristics and design philosophies. These architectures are widely used in processor design, but they have essential differences in instruction set structure, development background, and ecosystem. ARM (Advanced RISC Machine): The … Read more
Witness the Singularity of Technology Here Introduction: In the context of the rapid evolution of the semiconductor industry, the Instruction Set Architecture (ISA) has become the core hub of chip design. Traditional closed-source architectures such as ARM and x86 have long dominated the market, but with the rising demand for chip customization, power efficiency, and … Read more
Introduction: RISC-V (pronounced “risk-five”) is a new instruction set architecture (ISA) originally designed to support research and education in computer architecture. However, in recent years, it has evolved into a standardized, free, and open architecture for industrial implementations. One significant advantage of the RISC-V instruction set is its scalability, allowing users to select appropriate extension … Read more
A brief block diagram of a certain RISC-V Level 1 The storage architecture of RISC-V (from inside to outside): 1)Reg 2)TCM (Tightly Coupled Memory, divided into I/D) / LM (Local Memory, divided into I/D) 3)TLB lookup (Translation Lookaside Buffer, a fast cache of recent address mappings) – TLB hit: avoids Page Table Lookup – TLB … Read more
Our laptops conceal a secret blueprint that specifies the instruction set that the computer can execute, serving as an interface between hardware and software. These instructions are hidden behind proprietary technology and cannot be altered. However, starting from 2025, users may purchase a new type of laptop that is improved, with its secrets being public. … Read more
Introduction Some fans have asked me what ARM is, and they are confused about the relationships between concepts like Cortex, ARM cores, ARM architecture, ARM instruction set, and SoC. Below, I will clarify some concepts related to ARM. 1. ARM can be considered as a company name, a general term for a type of microprocessor, … Read more
