Abstract
A memory system is enabled to access data for multiple objects in an interleaved fashion. Object data is retrieved from a system bus via an input interface, is temporarily stored in a limited data memory of the memory system and object headers are stored in a header memory. Each object to be printed has an object header and may, or may not, have associated object data. A “skip” function is provided to terminate a transfer function if object data is not ready. The memory system is enabled to retrieve all data in an object or cancel the object before the endo f data is reached. An identifier is associated with each data object and is subsequently reused after the original data object is transferred or cancelled. A plurality of request levels are assigned each data request to indicate the urgency of a data request, enabling multiple memory systems to operate from a single data transfer function.
