Abstract

A computer system includes first and second subsystems. A
device is coupled to the second subsystem. The first subsystem is provided with a function for processing a request to access the device. The first subsystem is also provided with information for translating a format of the request. The information is transferred from the first subsystem to the second subsystem. Occurrence of the request is detected in the second subsystem. The format of the request is transformed referring to the information in the second subsystem. Thereafter, the request is processed in the second subsystem to access the device. The information may include first information for translating the logical address into a real address and second information for translating the file offset into a block address.
