Channel Synchronization in Assembly Language

section .data
    message db 'working...done', 0
    message_len equ $ - message

    global _start

_start:
    ; Print "working..."
    mov eax, 4
    mov ebx, 1
    mov ecx, message
    mov edx, 10
    int 0x80

    ; Sleep for 1 second
    mov eax, 162
    mov ebx, 1
    int 0x80

    ; Print "done"
    mov eax, 4
    mov ebx, 1
    mov ecx, message + 10
    mov edx, 4
    int 0x80

    ; Exit the program
    mov eax, 1
    xor ebx, ebx
    int 0x80

This Assembly Language code demonstrates a simple program that simulates synchronization. Here’s an explanation of what the code does:

1. We define a data section with our message “working…done”.

2. In the _start function (the entry point of our program):

   • We first print “working…” using the system call for writing to stdout (syscall 4).

   • Then, we use the nanosleep system call (syscall 162) to pause execution for 1 second. This simulates some work being done.

   • After the sleep, we print “done” using another write system call.

   • Finally, we use the exit system call (syscall 1) to terminate the program.

This code doesn’t use channels or goroutines as Assembly Language doesn’t have these high-level concepts. Instead, it directly uses system calls to achieve similar behavior.

To run this program:

1. Save the code in a file, e.g., sync.asm.
2. Assemble the code: nasm -f elf sync.asm
3. Link the object file: ld -m elf_i386 -o sync sync.o
4. Run the program: ./sync

The output will be:

working...done

Note that this Assembly code is for 32-bit Linux systems. Different architectures or operating systems might require modifications to the system call numbers and calling conventions.
