摘要： An input/output controller (39) is provided in a data processing system having a local memory bus (37), a main memory (35) coupled to this bus and a host central processing unit (33) also coupled to the bus. The input/output controller (39) interfaces a plurality of input/output devices to the local memory bus (37) and includes a plurality of input/output device controllers (41,43,45), each adapted to be connected to at least one input/output device. A single microprocessor (49) manages the operations of the input/output controller (39) and a single buffer memory (47) stores a program of instructions for the microprocessor and temporarily stores data passing to or from the input/output devices. A gate array (51) for interfaces the input/output device controllers (41,43,45) to the local memory bus (37).

摘要： A diskette identifying code is written in each sector on a flexible disk used in a flexible disk recorder. The diskette identifying code can be read from any track on the flexible disk and used to log the occurrence of insertion or removal of the diskette at the flexible disk recorder. Also, the diskette identifying code can be read from any accessed track prior to a write operation on that track in order to verify that the diskette has not been changed by the operator since the last access to the flexible disk.

摘要： The apparatus allows a single drive to serve two control lers which provide control signals on respective buses CBI(1) and CBI(2) (1609 and 1613) including RESERVE and RELEASE instructions. These instructions are applied to respective programmable logic arrays (PLAs 1601, 1603) which also receive signals fed back from state registers (1605, 1607). The registers include bits ERES1, ERES2 which are set when respective RESERVE Instructions are received and ERES2, ERES1 respective = 0, bits IRES1, IRES2 which are set when respective RESERVE instructions are received while ERES2, ERES1 respectively = 1 and INT1, INT2 which are set when ERES1, ERES2 = 1 and ERES2, ERES1 = 0 respectively. INT1 and INT2 send interrupts back to the respectively controllers and a controller which is thus enabled to use the drive does so in a succession of operations involving resetting of INT1, INT2 by a status control instruction from the controller. When the controller is finished it sends the RELEASE instruction to reset ERES1, ERES2 as the case may be. If a controller sends a RESERVE instruction, say on CBI(1), when the other controller is using the drive, i.e. ERES2 = 1, ERES1 is not set but IRES1 is set. When the other controller sends RELEASE and resets ERES2, this reset in conjunction with IRES1 = 1 causes ERES1 to be set. The combination ERES1 = 1 and ERES2 = 0 causes INT1 to be set, as above.

摘要： The system comprises a controller connected to a disk drive or drives by a bus including data lines and various control and handshaking lines. One line effects a CONTROL/DATA selection so that the drive knows whether codes sent on the data lines are disk data or drive control instructions. Another line effects a HEADER/DATA selection to distinguish the header and data portions of a disk sector. The controller includes a microprocessor (1911) with a register (1969) holding an expected header EHDR, a register (1967) holding the number SCOUNT of sectors to be read or written and a register (1965) holding the number of codes in a sector. in a read or write operation a signal CTLIDDCA from a sequencer (1945) select HEADER and a receiver, selected by a sequencer signal DP/INT, puts received codes on to a data bus (1913). The microprocessor (1911) receives sector headers in this way until there is a match, whereupon a signal CSIGS is given to the sequencer (1945) which causes CTL/DDCA to select DATA and DP/INT to enable the data receiver or driver depending upon whether the operation is read or write. The codes are counted down by decrementing DCOUNT. When DCOUNT = 0 (end of sector) SCOUNT is decremented and another signal CSIGS causes the sequencer to revert to the conditions for looking for the next expected header which is calculated by the microprocessor and entered in EHDR. Where SCOUNT reaches 0 the read or write operation is complete.

摘要： In an input/output control system: a read/write operation for a control register (REG) under a program mode is achieved by hardware; the system, per se, is started or stopped under the control of firmware, and a data transfer in the system is achieved under the control of hardware. Therefore, a high speed data communication is realized, via the system, between a central control unit (CC) and an input/output unit (10).

摘要： A computed tomography X-ray scanner employs a plurality of discs 56a-d which are asynchronously operated by controllers 58a-58d. A processor 54 either writes data in parallel into the same cylinder of different disc drives 56a-d and subsequently reads data in parallel from different cylinders of the discs into a memory unit 46, or writes data from the memory 56 in parallel to different cylinders of the disc drives 56a-d and reads data in parallel from the same cylinder of different ones of the disc drive, so that the data in converted from source fan format into detector fan format.

摘要： In a magnetic disc device, track bytes are added to a record which is to be stored in a cylinder of a magnetic disc in order to utilize an additional magnetic disc device of a different type in the same manner as the first-mentioned magnetic disc device. The magnetic device provides a means which checks track bytes read from the record for errors, which stores the track bytes in a track byte register (15) when they are correct, and which, when the stored track bytes are to be read out a later time, utilizes the contents stored in the track byte register (15) as track bytes of the record.

摘要： A secondary storage facility employing serial communications between drive (30) and controller (20). A dedicated cable (10) of four conductors is used to connect each controller/drive pair. Each conductor carries one undirectional channel. A first channel (16) is used for command messages and data sent from controller to drive. A second carries response messages and data from drive to controller (14). Third and fourth channels (18 and 12) carry real-time control signals from controller to drive and from drive to controller, respectively, indicative of controller and drive state, for ues in synchronizing and coordinating transmission. Each of the real-time state signals comprises a repeating bit pattern of predetermined pattern length; each bit in the pattern has a predetermined meaning. (Figs. 3, 4)
A multi-layered protocol is employed for controller- drive communications over the cable. The first level governs the electrical transmission of messages. Framing and data operations occur at a second level. A third level is used for command and response exchanges. The protocol is synchronous and supports variable length, multiple word messages, each bounded by specific beginning and end frames.
Specific command/response exchanges are identified. One is for communicating from the drive to the controller certain parametric information about the drive, which the controller must know to be able to use the drive. Another enables a host computer to selectively disable and enable the read-time drive state signals, to allow the host computer to determine all paths for accessing each drive with which it can communicate.
Each drive may employ multiple error recovery techniques; the controller signals the drive to try such techniques in sequence, according to descending a priori probability of success. The controller does not know or need to know the details of the error recovery procedures.
