Abstract

By appropriate arrangement of two sets of tables chosen to be complementary, cells which are conveyed through a first multiplexor, n RAM storages and the second are subject to a cell rearrange-ment enabling introduction of at least one bitmap field, thereby producing the n Logical Units. When two bytes which are processed in parallel have to be loaded at the same time in the same RAM storage, one particular byte is stored into one RAM available for a Write operation by use of the first set of tables, thereby causing an alteration to the normal association between the n RAMs and the n Logical Units which is then re-established by the second set of tables.
