A JavaScript assembly x86 compiler + emulator for educational purposes. I8086emu - a cross platform intel 8086 emulator Welcome to the official home page of the i8086emu - project i8086emu is an cross-platform emulator for the Intel 8086 microprocessor. It has support for dynamically loadable device plugins and some peripherals like a PIT, PIC, 8-segment-displays, buttons and leds. 8086 is 16-bit register. We can simply take the numbers from memory to AX and BX register, then subtract them using SUB instruction. When the Borrow is present, the CY flag will be 1, so we can store borrow into memory, otherwise only store AX into memory.
