Hello World in Assembly Language

Assembly Language for x86 Architecture

In assembly language, a simple “Hello, World!” program can be written like this (assuming we are using x86 architecture assembly language):

section .data      hello db 'Hello, World!',0    section .text      global _start    _start:      ; write syscall      mov eax, 4      mov ebx, 1      mov ecx, hello      mov edx, 13      int 0x80        ; exit syscall      mov eax, 1      xor ebx, ebx      int 0x80

This program first defines a string hello, and then uses a system call to output this string to the console. Finally, the program exits through another system call.

Note: This program can only run on systems that support x86 architecture and requires an environment capable of parsing and executing assembly code.

What is an x86 Architecture System?

An x86 architecture system refers to computer systems that use the x86 architecture. The x86 architecture is a complex instruction set used to control the operation of chips, typically introduced by Intel. The x86 architecture first appeared in the Intel 8086 CPU launched in 1978 and is now widely used in the home PC market. x86 architecture systems typically refer to computer systems that adopt the x86 architecture, including personal computers, servers, workstations, etc. These systems usually run operating systems like Windows or Linux and support various applications and software, capable of performing tasks such as office work, entertainment, gaming, etc. In summary, x86 architecture systems are widely used computer systems characterized by efficiency, reliability, and stability.

Assembly Language for x64 Architecture

Here is a simple “Hello, World!” program written in x64 assembly language:

section .data      hello db 'Hello, World!',0    section .text      global _start    _start:      ; write syscall      mov eax, 4     ; system call number (sys_write)      mov ebx, 1      ; file descriptor (stdout)      mov ecx, hello   ; pointer to the message      mov edx, 13      ; length of the message      int 0x80          ; invoke the system call        ; exit syscall      mov eax, 1       ; system call number (sys_exit)      xor ebx, ebx       ; exit code      int 0x80           ; invoke the system call

This program runs on x64 architecture computer systems and uses system calls to output the “Hello, World!” string and exit the program. Note that this program can only run on systems that support x64 architecture and requires an environment capable of parsing and executing assembly code.

What is x64 Architecture?

x64 architecture is a backward-compatible extension of x86, providing the same 32-bit mode and a new 64-bit mode. This architecture was first publicly introduced by AMD and is now also adopted by Intel. x64 extends the eight general-purpose registers of x86 to 64 bits and adds eight new 64-bit registers. Each register’s lower 32, 16, and 8 bits can be addressed directly. The x64 architecture supports more virtual and physical memory than the x86 architecture, allowing applications to store large amounts of data in memory. Additionally, x64 extends the number of general-purpose registers to 16, providing further enhancements and capabilities. The x64 architecture can use a total of 2^64 bytes, equivalent to 16 exabytes (16EB) of memory. Higher resource utilization makes it suitable for powering supercomputers and machines that need to access a large amount of resources. The x64 architecture allows the CPU to process 64 bits of data per clock cycle, far exceeding x86.

Assembly Language for ARM Architecture

Here is a simple “Hello, World!” program written in ARM assembly language:

.global _start    _start:      ; write syscall      mov r0, #1        ; file descriptor (stdout)      ldr r1, =hello      ; pointer to the message      mov r2, #13         ; length of the message      swi 1               ; invoke the system call        ; exit syscall      mov r7, #1           ; system call number (sys_exit)      swi 0                ; invoke the system call    .section .data      hello db 'Hello, World!',0

This program runs on ARM architecture computer systems and uses system calls to output the “Hello, World!” string and exit the program. Note that this program can only run on systems that support ARM architecture and requires an environment capable of parsing and executing assembly code.

What is an ARM Architecture System?

ARM architecture systems are computer systems that use the Advanced RISC Machine (ARM) architecture. The ARM architecture is a Reduced Instruction Set Computing (RISC) architecture, originally designed by Acorn Computer in the UK, and is now widely used in embedded systems, mobile devices, servers, and many other fields. ARM architecture systems are characterized by low power consumption, low cost, high performance, and high customizability and scalability. The application range of ARM architecture systems is very wide, including smartphones, tablets, e-book readers, digital TVs, gaming consoles, etc. These devices typically use operating systems like Linux and Android, supporting various applications and software, and can perform various tasks such as communication, entertainment, and office work. In summary, ARM architecture systems are efficient, low-power, low-cost computer systems with broad application prospects.
