ABSTRACT OF THE DISCLOSURE A data processing system which handles thirty-two bit logical ad- dresses which can be derived from either sixteen bit logical addresses or thirty-two bit logical addresses, the latter being translated into physical addresses by unique translation means. The system includes means for decod- ing macro-instructions of both a basic and an extended instruction set, each macroinstruction containing in itself selected bit patterns which uniquely identify which type of instruction is to be decoded. The decoded macro- instructions provide the starting address of one or more micro-instructions, which address is supplied to a unique micro-instruction sequencing unit which appropriately decodes a selected field of each micro-instruction to obtain each successive micro-instruction. The system uses hierarchical memory stor- age using eight storage segments (rings), access to the rings being con- trolled in a privileged manner according to different levels of privilege. The memory system uses a bank of main memory modules which interface with the central processor system via a dual port cache memory, block data transfers between the main memory and the cache memory being controlled by a bank con- troller unit.
