Operating System Design and Implementation: Based on LoongArch Architecture

Introduction:The rapid development of the IT industry has raised higher requirements for talent cultivation in universities. We can no longer be satisfied with producing talents who can only use foreign CPUs and operating systems; instead, we need to cultivate talents who can “create” their own operating systems. This is essential for achieving autonomy in the … Read more

Detailed Explanation of LoongArch Instruction Set: Compatible with MIPS/ARM/x86

A few days ago, Loongson announced the launch of the LoongArch instruction set, abandoning its previous MIPS licensing, featuring over 2,500 self-developed instructions, and capable of translating MIPS, ARM, and x86 instructions. For the development of domestic CPUs, there have always been two unresolved issues over the past 20 years: whether to pursue an independent … Read more

Video Explanation: Rolling Prediction of SPX Index Financial Time Series Volatility Using LSTM and GARCH

Full text link:https://tecdat.cn/?p=37371 This article integrates various technologies, among which the LSTM (Long Short-Term Memory) and GARCH (Generalized Autoregressive Conditional Heteroskedasticity) models are particularly crucial. LSTM excels in handling time series data, capturing long-term dependencies, and providing strong support for financial predictions. The GARCH model effectively captures the phenomenon of volatility clustering in financial time … Read more

Understanding the ISA Battle and Its Impact on CPU Architecture

by

(Source: hackday)The Instruction Set Architecture (ISA) defines the software interface through which a Central Processing Unit (CPU) can be controlled. Unlike early computer systems that lacked a defined standard ISA, the advantages of compatibility and portability with a standard ISA have become evident over time. However, the best part of standards is that there are … Read more
