ABSTRACT:
A scheduling device and a cell communication device capable of reducing a total storage region required for a scheduling function. Cell output control is performed by the scheduling function. The scheduling device includes a content addressable memory having queues for storing incoming cells. The queues have queue numbers. The queue numbers correspond to addresses of the content addressable memory. Read time for each cell is also stored in the content addressable memory. The actual time or a read time stored in a read time storage section is taken as the virtual time. The content addressable memory outputs a cell from a queue having a queue number indicated by an address, if this address has a matching address at the virtual time based on comparison conditions at the actual time and virtual time. The read time stored in the read time storage section and that in the content addressable memory are updated based on the comparison conditions at the actual time and virtual time.
