摘要： A data processing system includes a main memory system which couples in common with a central processing unit to a bus for transfer of data between the central processing unit and memory system. The memory system includes a plurality of memory controllers, each of which controls the operation of a number of memory modules. Each controller also includes reconfiguration apparatus for enabling reconfiguration of the memory system upon detection of a fault. The reconfiguration apparatus includes apparatus for identifying the type and design revision of the controller associated therewith enabling more expeditious fault diagnosis based upon status signals provided by the controller during diagnostic testing by the central processing unit.

摘要： A memory system includes at least one or more memory module boards identical in construction and a single computer board containing the control circuits for controlling memory operations. Each board plugs into the main board and includes a memory section having a number of rows of memory chips and an identification section containing circuits for generating signals indicating the board density and the type of memory parts used in constructing the board's memory section. The main board control circuits include a number of decoder circuits which couple to the identification and to the memory section of each memory module board. The decoder circuits receive different address bit combinations of a predetermined multibit address portion of each memory request address. In response to signals generated by the identification sections of the installed memory boards, the decoder circuits are selectively enabled to decode those bit combinations of the address portion specified by the sections for enabling successive addressing of all of the blocks of location within the system.

摘要： A memory subsystem which couples to a multiword bus for processing memory requests received therefrom includes at least a pair of independently addressable dynamic memory module units. Each memory unit includes a number of rows of random access memory (RAM) chips. The subsystem further includes an adder circuit, a pair of tristate operated address register circuits and timing circuits. The address circuits include a pair of tristate operated address registers which couple to the bus and to the set of address lines to each memory unit. In response to a memory request, the registers store row and column address portions of a chip address of the memory request. A multibit adder circuit which couples to the bus is connected to increment by one the low order column address portion when the least significant address bit of the memory request indicates a subboundary address condition thereby enabling access to a pair of sequential word locations. Whenever a memory request specifies an address which cannot access a double word, boundary circuits upon detecting the condition cause the timing circuits to generate only timing signals necessary for accessing the first word location.

摘要： A single computer board data processing system includes a multiport memory system which is accessible by I/O controllers through a system bus I/O memory port or directly by the system's central processing unit (CPU) via a CPU memory port. The logic and control circuits of the memory ports and CPU are included within the computer main board while memory modules/pacs are contained on one or more memory daughter boards which plug into memory input/output connectors contained on the main board. The port address and data paths connect in common to the memory connectors for transmitting and receiving memory addresses and data between the memory modules and the CPU and I/O ports. At least one register connects between the CPU and to common address path. When the CPU is placed in a diagnostic mode of operation, this register together with existing data registers are conditioned to store signals representative of the address and data being transmitted to the memory modules enabling the CPU to diagnose whether the main board or portions thereof has failed without requiring any testing of the memory modules.

摘要： A method for determining the maximum amount of physical memory present in a data processing system that can be configured to have one or more memory modules where the memory modules may be one of several types having different amounts of memory locations. By having signals indicating the presence of a memory module and the module type directly available with minimal intervening logic, a diagnostic process can accurately determine the amount of memory present in the system and reduce the possibility of a failed memory module going undetected. A method is also descibed using these memory module present and module type signals for detecting an attempt by either the central processor or an input/output controller to access a memory location that is not physically present within the data processing system.

摘要： A data processing system including a dual ported main memory that can be accessed by I/O controllers via a common bus or directly by the central processing unit. The main memory is comprised of a volatile RAM array that requires periodic refreshing to prevent loss of information. Access to the main memory is controlled by a priority resolver that awards access to the main memory on the basis of predetermined priority levels assigned to CPU, I/O and refresh requests. The priority resolver produces an early signal that is usable to initiate a memory cycle before the final winner of the main memory is determined. The logic path of the lowest priority requester is the shortest path thus allowing the lowest priority requester to initiate a memory cycle in the shortest amount of time even though another requester may ultimately win use of the memory. The priority resolver also provides for the early resetting of access requests so that subsequent requests can be made with minimum delay. Logic is provided that allows the predetermined priority levels to be adjusted dynamically as a function of system conditions.

摘要： In accordance with the present invention, there is provided a system for logging an error that occurred in a multi-chip memory storage device in a data processing system. The system has a mechanism for detecting an error and for receiving data and check bits associated therewith. The mechanism for detecting an error generates syndrome bits as a function of the data and of the check bits. Connected to the error detecting mechanism is an error logging mechanism which is adapted to receive the syndrome bits and to determine the chip in which the error occurred.
