Abstract
A shared resource system (20) is disclosed wherein multiple user devices (24) share a resource device such as a disk drive (36). The multiple user devices (24) are interconnected to the resource device by high speed synchronous serial data links (26). Each of the user devices (24) include a serial to parallel/parallel to serial converter means (22) for converting and transmitting on the high speed synchronous serial data links (26) user device requests to access the resource device. The resource device includes a serial to parallel/parallel to serial converter means (30) for converting and transmitting such user device requests on a parallel data bus to the resource device. The resource device converter means (30) including multiple access ports (54) to enable multiple user devices (24) to access the resource device, the converter means (30) individually and periodically polling each of the access ports (54).
