cpu-emulator

Experimental CPU emulator written in C

Goals

• Learn more about CPU emulation
• Build a compiler
• Build a unix-like operating system
• Build a filesystem
• Build a network stack
• Implement Unix tools usually found in /bin (ls, cat, etc)
• Implement a simple web server
• Run a CPU emulator inside another emulator

Architecture

CPU

typedef struct cpu_t {
    // Registers
    uint8_t  A;         // Accumulator register
    uint16_t I;         // Memory address register
    uint16_t PC;        // Program counter register
} cpu_t;

Full system (CPU + memory)

typedef struct system_t {
    cpu_t *cpu;
    uint8_t memory[MEMORY_SIZE];
} system_t;
