Abstract
A peripheral device control system comprises a processor, a first bus, and a bridge device. The processor comprises a set of control instructions. The first bus couples to the processor by the first bus protocol. The bridge device communicates with the first bus by the first bus protocol and communicates with the peripheral device by a second protocol, wherein the processor transmits a set of control instructions to the peripheral device through the first bus and the bridge device, so as to directly control the peripheral device to perform a specific function.
Claims14
A system for controlling a peripheral device, the system comprising:
- a processor generating a set of control instructions;
- a first bus coupling to the processor and transmitting the set of control instructions according to a first bus protocol;
- and
- a bridge device communicating with the processor through the first bus according to the first bus protocol and communicating with the peripheral device through a second bus according to a second bus protocol;
- whereas the processor transmitting the set of control instructions from the first bus, the bridge device, and the second bus to the peripheral device, and directly controlling the peripheral device to perform an operation.
A computer system, the computer system comprising:
- a peripheral device;
- a processor generating a set of control instructions;
- a first bus coupling to the processor and transmitting the set of control instructions to the first bus;
- and
