An ATM information system processes information at the frame level using a processor including a device driver; a system memory and an adapter for sorting data cells into partially completed frames stored in the system memory using control information provided by the device driver. A controller in the adapter determines when an end of frame indication is received in a cell and updates a pointer in system memory for a completed frame list to a recently completed frame. The device driver processes frames in a completed frame list according a priority of the list. The device driver processing is independent of the sorting and storing of completed frames received in the system memory which improves the performance of the driver and the ability to handle delay sensitive traffic.

[ What is claimed:] [1.] An information system including a system processor with memory and an adapter for receiving data cells and reassembling the cells into sorted prioritized frames in system memory whereby the system can process information at the frame level comprising:means for supplying to the adapter virtual circuit control information including prioritized frame sort information for a plurality of data sources;means for receiving and sorting cells into partially completed ATM frames in a first area of the system memory according to the virtual circuit control information;means for determining when an end of frame indication is received in a cell;means for linking completed frames onto one of a plurality of received ready lists in a second separate area of the system memory according to a priority of the list;means for updating a pointer in the system memory for a prioritized completed frame list through a most recently completed frame; andmeans for serving the data sources with frames according to the highest priority data source.
