    摘要： A cache memory wherein data words identified by odd address numbers are stored separately from data words identified by even address numbers. A group of diagnostic control registers supply signals for controlling the testing of the cache within the cache memory to determine the operability of the individual elements included in the cache memory.

    摘要： Signals representing the past and present states of a condition under test during an instruction execution cycle, as well as a signal indicating that an execute cycle has taken place, are utilized as address signals applied to a memory which feeds an output to control a bistable element. The bistable element is set to the state of the memory output signal and supplies the address signal indicative of the past state of the condition under test. The memory is coded to respond at its output with signals controlling the bistable element such that once a given state of the condition under test is detected and stored in the bistable element, the latter is inhibited from switching regardless of any further changes in the condition under test during the current instruction execution cycle.

    摘要： A control store in a data processor is addressed by means of next address generation logic which includes a first multiplexer utilized to address the control store, which multiplexer has several inputs. One of such inputs is received from a latching mechanism which allows more than one test condition to be simultaneously utilized for addressing the control store on a free flow basis. These test conditions, as well as information from an addressed control word, are utilized in a multiplexed arrangement as one input of the first multiplexer. By use of other inputs of such first multiplexer, the control store may be addressed by use of branch address information, as well as other test condition information. A page register provides the page address, to a plurality of pages included in this control store with the locations in each such page addressed by use of the above noted multiplexer combination.

    摘要： Information from a main data processor is transferred to an auxiliary data processor of the system and is stored in a control file which may be addressed by either a firmware word from a control store or by use of the function code received in an instruction from the main processor. Information in such control file is used for the purpose of addressing main memory. The address for main memory may be incremented or decremented simultaneously as operands are being fetched from main memory for execution.
