Starting from the new paradigm of AI, the AX8850 opens a new era of high-efficiency AI processing. In the current global wave of artificial intelligence, the consensus that “AI is everywhere” has emerged. However, how to popularize AI in edge scenarios with lower costs and higher energy efficiency has become a key competition among chip … Read more
In February 2025, the chip IP provider Arm announced the launch of its first self-developed chip, a news that has caused a strong shock in the global semiconductor industry. As a leading company in the chip architecture field, Arm is transitioning from a traditional IP licensing model to a strategy of self-designed and manufactured chips, … 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
Central Processing Unit (CPU) The CPU generally consists of a logic unit, a control unit, and registers, serving as thecore of computation and control in a computer. The CPU’s control unit retrieves executable code from memory and converts it into executable instructions, which are then processed by the arithmetic unit. The CPU can be applied … Read more
SIMD has played an increasingly important role in processors in recent years, providing significant performance improvements for multimedia applications, and most computations within GPGPU warps are also performed in a SIMD-like manner. Understanding SIMD is crucial for a comprehensive understanding of architecture. This book provides a comprehensive and detailed introduction to the design concepts and … Read more
RISC-V is also known as “the Linux of CPUs.” For some, this title feels like a legacy and an innovation at the same time, especially if you are a staunch believer in open source. However, I am a true pragmatist, and the excessive marketing of RISC-V has made me lose interest in the term. It … Read more
This article is excerpted from “2022 Research Framework for Domestic Server CPUs“. In the post-Moore’s Law era, the performance benefits brought by the improvement of process technology are already very limited. The Dennard Scaling law constraints have led to a sharp increase in chip power consumption, and the cost of transistors has risen instead of … Read more
Author: Huang Yefeng Original from EET Electronic Engineering Magazine Processors based on the RISC-V architecture are increasingly appearing in everyday electronic products, becoming more commonplace: not only have some typical MCU manufacturers begun to embrace RISC-V, such as the previously interviewed Tsinghua Unigroup, but also companies like GigaDevice have launched RISC-V product lines; Moreover, this … Read more
The Cortex A77 architecture, newly launched by Arm in May 2019, utilizes TSMC’s 7nm process with a peak frequency of 3GHz, achieving a 20% performance improvement. A previous article introduced the architecture of the strongest X86 processor, ZEN, which can be found here. This article analyzes the strongest Arm processor, A77, based on the same … Read more
Source: Chip Theory Abstract: Previous articles have mentioned that there are many classification methods for chips, with varieties as numerous as the stars in the night sky, making it impossible to enumerate them all. This article narrows the focus to high-end general-purpose chips, specifically CPUs. We will find that there are also many types of … Read more
