This paper describes serialization support in an object oriented Java processor like jHISC. The relevance of serializing an object confines to situations when an object has to be sent over network or stored as a persistent object. But these are not rare scenarios when an application in a mobile device is considered. This paper proposes a serialization functional unit which consists of a serialization unit and deserialization unit along with descriptors and pool to describe and store serialized objects. This design can enhance the performance of Java based mobile devices which runs applications those communicate with similar applications very often. This design makes use of architectural features of processors like jHISC. This design can contribute much to Java based mobile computing in the near future.
