摘要： A data processing system having a plurality of units includes a shareable unit which is shareable between two or more of the other units. Lock apparatus is provided in the shareable unit to allow a first unit to lock the shareable unit so that no other unit attempting to lock the shareable unit will be permitted access to the shareable unit. The lock apparatus includes means that permit two units desiring to lock the shareable unit to make simultaneously asynchronous requests to lock the shareable unit. The lock apparatus further includes means to permit the unit which has locked the shareable unit to unlock the shareable unit so that it becomes available for a subsequent lock by a unit. The lock apparatus also includes means to allow the shared unit to be accessed by other units not attempting to lock the shareable unit even when the shareable unit is locked.

摘要： In a data processing system, a bus is provided for the transfer of information between units coupled to the bus. The units are coupled in a priority arrangement which is distributed thereby providing priority logic in each of the units and allowing bus transfer cycles to be generated in an asynchronous manner. Priority is normally granted on the basis of physical position on the bus, highest priority being given to the first unit on the bus and lowest priority being given to the last unit on the bus. Each of the units includes priority logic which includes logic elements for requesting a bus cycle, such request being granted if no other higher priority unit has also requested a bus cycle. The request for and an indication of the grant of the bus cycle are stored in each unit so requesting and being granted the bus cycle respectively, only one such unit being capable of having the grant of a bus cycle at any given time, whereas any number of such units may have its request pending at any particular time. A modification to the priority logic allows a lowest priority unit to be physically positioned at other than the last unit position on the common bus.

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： 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 data processing system includes an asynchronous parallel multiport volatile main memory system accessible directly by any one of M number of central processing units or by I/O controllers connected in common to any one of N number of system buses. Priority resolver circuits award access to main memory on a predetermined priority basis.

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.
