Core Architecture

Low-Level Optimization

Hand-crafted assembly routines and C code optimized for minimal CPU cycles and memory footprint.

Memory Management

Advanced paging system with custom allocators for efficient memory utilization and security.

Preemptive Scheduler

Priority-based task scheduling with real-time capabilities and context switching optimization.

Ring-0 Security

Kernel-level protection with privilege separation and secure system call interface.

Device Drivers

Modular driver architecture with support for PCI, USB, and legacy hardware interfaces.

Network Stack

TCP/IP implementation with socket API and optimized packet processing pipeline.

void kernel_main(void) {
    // Initialize core subsystems
    memory_init();
    scheduler_init();
    interrupt_init();
    
    // Mount root filesystem
    vfs_mount("/dev/sda1", "/", "ext4");
    
    // Start init process
    process_create("/sbin/init", KERNEL_PRIORITY);
    
    // Enter scheduler loop
    while(1) {
        schedule();
    }
}
