Abstract
A system including a serialized secondary bus architecture. The system may include an LPC bus, an I/O controller, a serialized secondary bus, and at least one slave device. The LPC bus may be connected to the I/O controller, and the at least one slave device may be connected to the I/O controller via the serialized secondary bus. The serialized secondary bus has a reduced pin count relative to the LPC bus. The I/O controller may receive bus transactions from the LPC bus. The I/O controller may translate and forward LPC bus transactions to the at least one device over the secondary bus. The I/O controller may include a processing unit. The processing unit may initiate bus transactions intended for the at least one slave device. The I/O controller may also include a bus arbitration unit. The bus arbitration unit may arbitrate ownership of the secondary bus between the processing unit and the LPC bus.
