After introducing memory virtualization technology, there are three types of addresses in the memory system. Machine Address (MA): The real hardware machine address, visible on the address bus as address signals. Guest Physical Address (GPA): The pseudo-physical address seen by the virtual machine after abstraction by the VMM. Virtual Address (VA): The linear address space … Read more
In recent years, more and more enterprises have begun to focus on the development of new IT solutions, with “virtualization” being one of the key areas of concern in this process. Especially during the transition of enterprise IT infrastructure from traditional architectures to distributed architectures, adopting a self-controlled virtualization system can achieve a dual benefit. … Read more
Introduction Virtualization in computers is a vast topic with a long history, and here we will introduce some concepts. 01 Definition of Virtualization Virtualization is the process of creating a software-based or virtual representation of something, essentially creating a virtual version of something, such as virtual applications, servers, storage, and networks. Computing components run on … Read more
Produced by | Furui Microelectronics Overview of Virtualization 1.1 Drivers and Advantages Virtualization is a widely used technology that supports nearly all modern cloud computing and enterprise infrastructure. Developers can run multiple operating systems on a single machine based on virtualization capabilities, allowing software testing without risking damage to the primary computing environment. Virtualization brings … Read more
With the development of ICT technology, a single SOC’s computing power can undertake more services. The expansion of network bandwidth and features such as low latency and differentiated services make business deployment and function allocation more flexible. For example: perception, fusion, planning, control, and execution can be decoupled. The electronic and electrical architecture transitions from … Read more

The previous article introduced the basic concepts of virtualization and hypervisors. To facilitate virtualization, ARM has done a lot of work, primarily defining four Exception Levels (EL). As mentioned in earlier articles about exceptions and privileges, I will elaborate a bit more here. Each exception level is numbered, ranging from EL0 to EL3, with higher … Read more
