METHOD OF AND DEVICE FOR WRITING AND READING DATA ITEMS IN A MEMORY SYSTEM

摘要

Data items associated with different locations in a spatial field of locations are written in a memory. The memory comprises a length memory in which for each location there is stored a length code which indicates the memory length required for the data item. For the reading of a data item associated with a location, the address of the data item is calculated by reading the length codes for the data items of preceding locations from the memory and by summing the lengths indicated.
