CPU Section 1. CPU Architecture The CPU architecture currently lacks a definitive and authoritative definition. Simply put, it refers to the design scheme of the CPU core. CPUs can generally be classified into various architectures such as X86, IA64, RISC, etc. The CPUs found in personal computers are essentially designed based on the X86 architecture, … Read more
Previously, it was explained that when external registers need to be added, the bus interconnection module must be changed. In the bus interconnection module, each register has a wire connected to the bus interconnection module for reading data and enabling signals. If there are relatively few registers, it seems there is no problem. But what … Read more
As cars enter the era of electrification and intelligence, the terminology arising from product transformation confuses consumers. For instance, terms related to chips such as CPU, GPU, NPU, SoC, etc. These parameters are particularly important, even rivaling some core component configurations from the era of fuel vehicles. This time, we will conduct a popular science … Read more
After more than 50 years of absolute dominance, the CPU is finally facing new challenges, with the challenger being the SoC. In the past decades, you could walk into any computer store and choose a brand new computer based on CPU performance. Now, whether you look at smartphones, tablets, or laptops, they are all starting … Read more
You’ve Come This Far Don’t You Want to Know More? Recently, I’ve seen many people in the industry asking how to verify CPUs and what SOC verification involves. Today, I will briefly introduce IP, FPGA, SOC, and CPU verification. A typical chip team is composed of several departments: the Architecture department, IP designer department, IP … Read more
Click the above PC Enthusiasts to follow us At the end of last year, Qualcomm tailored the Snapdragon 8cx Gen3 computing platform for “Windows on ARM”, which uses a 5nm process and consists of 4 cores of 3.0GHz Cortex-X1 super large cores and 4 cores of 2.4GHz Cortex-A78 large cores. Compared to the previous generation, … Read more
Source: Software-Hardware Integration Author:Chaobowx 1 Software and Hardware 1.1 Definitions of Software and Hardware Instructions are the medium between software and hardware, and the complexity of the instructions determines the degree of decoupling between the system’s software and hardware. Based on the complexity of unit calculations (instructions), processor platforms can be roughly divided into CPU, … 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
Click the top Computer Enthusiasts to follow us With the release of the Kirin 9000 and Samsung Exynos 1080, the Android smartphone chip sector has officially entered the 5nm era. Unfortunately, the CPU architecture of the Kirin 9000 still lingers at the ARM Cortex-A77 stage released last year, while the Exynos 1080, although equipped with … Read more
