Memory management in packet data mode systems.

摘要

This invention is a memory management system for a packet data mode system which is used in conjunction with a direct memory access controller. The management system is of the type for communicating packet data into and out of memory storage. Each message in a packet data mode system contains a control address field and a data field. The invention includes means for generating a change of field signal and for communicating that signal to the DMA controller. The invention also includes means for generating an end of message signal with means for communicating the end of message signal to the DMA controller. The contrcl address field is stored separately from the data field. This increases the efficiency of the data storage and enhances the density of information packing into the memory storage.
