Low Level Programming Language
Assembly, hardware-level programming language. It is used in system programming, embedded systems and performance-critical applications.
Assembly language development process and important turning points
Assembly languages were developed as an alternative to machine code for the first computers.
The first assembler programs were developed to convert assembly code into machine code.
Assembly languages were standardized for microprocessors such as Intel 8080 and Motorola 6800.
Advanced assembly languages for modern architectures like x86-64, ARM, and RISC-V.
Distinguishing features and advantages of the assembly language
Maximum performance is achieved by direct access to hardware. It works without unnecessary layers.
fast addition process
mov eax, 10
add eax, 20
mov [result], eax
It provides full control over hardware resources. Direct access to registers, memory and I/O ports.
in al, 0x60
out 0x20, al
cli
sti
Only the necessary operations are performed without unnecessary overhead. Small and efficient programs.
mov ecx, 10
loop_start:
dec ecx
jnz loop_start
You can fully control memory usage. Manual memory management and optimization.
mov eax, [ebp+8]
lea ebx, [eax*4+offset]
mov [ebx], 42
Low-level debugging capabilities. You can control system calls and interrupts.
int 3
pushf
popf
nop
Ideal for system security and cryptographic applications. Low-level security control.
xor eax, eax
rep stosb
mfence
