Managing data flow between a serial bus device and a parallel port

摘要

The present invention is directed to a method and apparatus for managing data flow between a serial bus device which operates at a first data rate and a parallel port device which operates at a second data rate. A serial bus receiver receives data from the serial bus device at the first data rate. A buffer unit is coupled to the serial bus receiver and the parallel port device. The buffer unit stores the received data at the first data rate and transfers the stored data to the parallel port device at the second data rate.
