Title: Electronic service request system
IPC: G06F15/167
Filed: 1968-06-25
Abstract: 1,217,354. Priority circuits. INTERNATIONAL BUSINESS MACHINES CORP. 25 June, 1968 [7 July, 1967], No. 30173/68. Heading G4A. An electronic service request system includes first and second registers, first gating means for passing received request signals to the first register and second gating means for passing the contents of the first register to the second register, inhibit signals preventing operation of the first and second gating means a predetermined delay after detection of registration of request signals in the first and second registers respectively. Priority circuit.-Four communication channel control units and four processors constitute odd-numbered 1, 3, 5, 7 and even-numbered users 2, 4, 6, 8 respectively, of a storage unit, storage access requests from the users being honoured one at a time by the circuit of Fig. 2. Each odd-numbered user has three latches 31, 33, 40 and in some cases a high-priority latch 36. Each even-numbered user has three latches 68, 70, 62. Only the latches for users 1, 2 are actually shown. An access request from an oddnumbered user on its line 30 sets its latch 31 and this, provided no latch 33 is set, sets its latch 33 via AND 32. If the user has a latch 36 and the access request is of high priority it also energizes its line 35 to set its latch 36 via AND 37. The user's latch 40 can be set (a) via AND 43 from its high priority latch 36, (b) via AND 42 from its latch 33 provided no high priority latch 36 is set, or (c) via AND 41 from its latch 31 provided no high priority latch 36 is set and provided no latch 33 is set. However, due to an inverter 49 &c., setting of the user's latch 40 is prevented if the storage unit is still busy with the previous request or if any of the latches 40, 62 is already set (subject to circuit delays). An access request from an even-numbered user on its line 60 can result in setting of its latch 62 under similar conditions except that the highpriority feature involving latches like 36 is absent in the case of the even-numbered users, and setting is also possible via AND 61 direct from line 60 provided no latch 68 is set. Tie break logic 50 selects the highest priority user which has its latch 40 or 62 set giving priority to the odd-numbered group of users over the even-numbered, and the priority within each group being preset manually using jumper connections. When the highest priority user has been selected and serviced, the latches 31, 33, 36 or 68, 70 relating to that user, and all the latches 40, 62 are reset. As a modification, the outputs from the high priority latches 36 can disable the even-numbered user ANDs 61, 65, 66. Specification 1,217,355 is referred to for means for reducing the time required for tie breaking. Error detection in the priority circuit.-If more than one output occurs from the tie break logic 50 at a time, the latches 40, 62 are reset and another priority resolution attempted. If more than one output is produced again, an error signal is generated.
