x86、x64 和 ARM64 体系结构概述
x86 架构:作为一种 32 位架构,其历史可追溯到 1978 年英特尔推出的 8086 微处理器。当时,它是一个 16 位处理器,内存寻址容量仅为 1MB。随后的 80286 添加了保护模式,使其能够寻址 16MB 内存。80386 成为第一款真正的 32 位 x86 处理器,配备了多任务处理和虚拟内存管理功能。x86 体系结构具有 32 位通用寄存器,理论上,其最大内存寻址空间为 4GB。它一次可以处理 32 位数据,指令集相对简单,适用于早期的个人计算机以及资源要求较低的小型设备和软件,例如 Windows 98 系统和简单的文本编辑软件。
x64 架构:它是 x86 架构的 64 位扩展。2003 年,AMD 率先推出了 AMD64 架构,Intel 随后推出类似的 EM64T 架构。x64 架构将通用寄存器扩展到 64 位,从而把可寻址内存空间显著增加到 TB 级。它一次能够处理 64 位数据,再加上更复杂的指令集,在多任务处理和处理大型数据集方面具备显著的性能优势。它广泛应用于现代个人电脑、服务器、高端工作站等,例如运行 64 位版本的大型数据库软件(如 Oracle)和专业图形设计软件(如 Adobe Photoshop)。
ARM64 架构:它是 ARM 架构的 64 位版本。ARM 长期专注于低功耗和低成本芯片的设计,在移动设备市场占据主导地位。ARM64 架构采用精简指令集计算机(RISC)设计,可以用更少的指令完成基本操作,从而降低功耗。它拥有相对大量的 64 位寄存器,可实现高效的数据处理并支持较大的内存寻址空间。除移动设备外,它还广泛用于物联网(IoT)设备、嵌入式系统和一些云计算场景。例如,树莓派开发板和一些云服务器采用 ARM64 架构,以实现高性能和低功耗。
安装 x64、x86 和 ARM64 的必要性 - 相关组件
软件兼容性:在计算机的发展历程中,诞生了大量基于 x86 架构开发的软件应用程序。这些软件程序针对 32 位系统和 x86 指令集进行了优化,需要 x86 组件来提供支持。对于 x64 软件,必须安装 x64 组件,才能充分利用 64 位体系结构的高性能优势。对于 ARM64 架构,移动设备上的软件以及为 ARM64 平台开发的软件,只有在安装了相关的 ARM64 组件后才能正常运行。如果未安装相应的架构组件,软件可能会因无法识别和调用底层系统资源而出现兼容性问题,甚至可能无法启动。
DLL 依赖项:现代软件依赖大量动态链接库(DLL)文件。这些 DLL 可能来自不同的开发人员,且具有不同的体系结构版本。例如,软件的主程序可能是 x64,但它调用的插件或库可能是 x86。在移动开发中,软件调用的库可能是 ARM64 架构。如果缺少对应架构的 DLL 组件,软件在运行时可能会因找不到或无法加载所需的 DLL 文件而崩溃,并可能出现“找不到指定的模块”等错误提示。
性能优化要求:x64 组件使 64 位软件能够在支持 64 位操作的硬件上直接访问更大的内存空间,避免了 32 位架构的内存限制问题,进而提高运行速度。x86 组件为系统中的 32 位软件提供了适宜的运行环境,防止在 64 位环境中运行 32 位软件时出现性能下降。ARM64 架构允许基于其开发的软件在移动设备和其他硬件上利用其低功耗和高性能特性,并根据不同的任务和场景充分发挥其寄存器和指令集的优势。如果未安装合适的架构组件,就无法针对硬件架构进行软件优化,可能会出现运行缓慢、卡顿等性能问题。
系统环境完整性:Windows 系统包含大量系统级 DLL 文件。安装 x64 和 x86 组件能够保证系统环境的完整性。在 Linux 等系统中,对于采用 ARM64 架构的设备,安装 ARM64 相关组件对于确保系统软件和应用程序的稳定运行同样至关重要。如果在系统更新或软件安装过程中,没有正确安装相应的架构组件,可能会导致系统中出现版本不匹配或缺少 DLL 文件的情况,从而引发蓝屏死机或系统卡顿等系统故障。由于系统环境不完整,软件也会运行异常。

Overview of x86, x64, and ARM64 Architectures
x86 Architecture: As a 32 - bit architecture, its history can be traced back to the 8086 microprocessor launched by Intel in 1978. At that time, it was a 16 - bit processor with a memory addressing capacity of only 1MB. The subsequent 80286 added the protected mode, enabling it to address 16MB of memory. The 80386 became the first true 32 - bit x86 processor, equipped with multitasking and virtual memory management capabilities. The x86 architecture has 32 - bit general - purpose registers. Theoretically, its maximum memory addressing space is 4GB. It can process 32 - bit data at a time, and its instruction set is relatively simple. It was suitable for early personal computers and small - scale devices and software with low resource requirements, such as the Windows 98 system and simple text - editing software.
x64 Architecture: It is a 64 - bit extension of the x86 architecture. In 2003, AMD took the lead in launching the AMD64 architecture, and Intel subsequently introduced the similar EM64T architecture. The x64 architecture extends the general - purpose registers to 64 bits, significantly increasing the addressable memory space to the terabyte level. It can process 64 - bit data at a time. Coupled with a more complex instruction set, it has significant performance advantages in multitasking and handling large data sets. It is widely used in modern personal computers, servers, high - end workstations, etc., such as running 64 - bit versions of large - scale database software like Oracle and professional graphic design software like Adobe Photoshop.
ARM64 Architecture: It is the 64 - bit version of the ARM architecture. ARM has long focused on the design of low - power - consumption and low - cost chips and dominates the mobile device market. The ARM64 architecture adopts a Reduced Instruction Set Computer (RISC) design, which can complete basic operations with fewer instructions to reduce power consumption. It has a relatively large number of 64 - bit registers, enabling efficient data processing and supporting a large memory addressing space. In addition to mobile devices, it is also widely used in Internet of Things (IoT) devices, embedded systems, and some cloud - computing scenarios. For example, the Raspberry Pi development board and some cloud servers adopt the ARM64 architecture to achieve high - performance and low - power consumption.
Necessity of Installing x64, x86, and ARM64 - related Components
Software Compatibility: Throughout the development of computers, a large number of software applications have been developed based on the x86 architecture. These software programs are optimized for 32 - bit systems and the x86 instruction set and require x86 components for support. For x64 software, installing x64 components is necessary to fully leverage the high - performance advantages of the 64 - bit architecture. Regarding the ARM64 architecture, software on mobile devices and those developed for the ARM64 platform can only run properly when the relevant ARM64 components are installed. If the corresponding architecture components are not installed, software may encounter compatibility issues due to its inability to recognize or call underlying system resources, and may even fail to start.
DLL Dependency: Modern software relies on numerous Dynamic - Link Library (DLL) files. These DLLs may come from different developers and have different architecture versions. For example, the main program of a software may be x64, but the plugins or libraries it calls may be x86. Or in mobile development, the libraries called by the software may be of the ARM64 architecture. If the DLL components of the corresponding architecture are missing, the software may crash during runtime because it cannot find or load the required DLL files, and error messages such as "The specified module could not be found" may appear.
Performance Optimization Requirements: x64 components enable 64 - bit software to directly access a larger memory space on hardware that supports 64 - bit operations, avoiding the memory - limitation problems of the 32 - bit architecture and improving the operation speed. x86 components provide a suitable operating environment for 32 - bit software in the system, preventing performance degradation when running 32 - bit software in a 64 - bit environment. The ARM64 architecture allows software developed based on it to utilize its low - power - consumption and high - performance characteristics on mobile devices and other hardware, and fully exploit the advantages of its registers and instruction set according to different tasks and scenarios. If the appropriate architecture components are not installed, the software cannot be optimized for the hardware architecture, and performance problems such as slow running and freezing may occur.
System Environment Integrity: The Windows system contains a large number of system - level DLL files. Installing x64 and x86 components can ensure the integrity of the system environment. In systems like Linux, for devices with the ARM64 architecture, installing ARM64 - related components is equally crucial to ensure the stable operation of system software and applications. If, during system updates or software installations, the corresponding architecture components are not installed correctly, it may lead to version mismatches or missing DLL files in the system, triggering system failures such as the blue - screen of death or system freezes. Software will also run abnormally due to the incomplete system environment.
