A hardware control method and a hardware control system. The hardware control method is for an operating system to control at least one function circuit. The hardware control method includes: converting a first virtual address and a second virtual address from the operating system to a first intermediate address and a second intermediate address, respectively; converting the first intermediate address and the second intermediate address to a first extended physical address and a second extended physical address, respectively, wherein a starting position of the first extended physical address is distanced by a gap from a starting position of the second extended physical address; and converting the first extended physical address and the second extended physical address to a first hardware physical address and a second hardware physical address, respectively, wherein the first hardware physical address is adjacent to the second hardware physical address.
