Title: Improvements in or relating to stored program data processing machines
Inventor: ECKHART BARRY JACK
IPC: H04Q3/545
Filed: 1968-06-13
Abstract: 1,235,325. Digital electric data processor. WESTERN ELECTRIC CO. Inc. 13 June, 1968 [14 June, 1967], No. 28208/68. Heading G4A. Stored program data processing machine has a plurality of logic means each adapted to process a respective class of work, a plurality of storage locations each of which is adapted to store requests for performing a respective one of the classes of work, means for interrupting the processing of any of the classes of work to process a class of work of higher priority, means for determining the period from the interruption to the recommencement of processing of a first class of work and means responsive to the determining means to regulate the number of items to be taken from a storage location to perform work of another class. A processing machine of the kind described in Specifications 1,081,811 to 1,081,817 performs 8 base level jobs in the order EABACABADAB ACABAE and has interrupts of various priorities, an interrupt J being performed every 5 m.secs. Every twenty-fourth J interrupt, i.e. every 120 m.sec. path 245 (Fig. 2) is activated. This commences a programme designed to determine the time between E level jobs and to reduce this time if it has taken longer than a predetermined time by decreasing the amount of work done in the D level. Each level has a hopper storing work requests and more or less requests may be extracted from the hopper depending on the time lapse occurring between the E levels. If during a J level interrupt the E revisit time average over the last three visits is more than 1 second the calling rate is reduced 6% and if more than 1À8 seconds the system is placed in an overload state wherein scanning for new requests is omitted. If more than 8 seconds is taken emergency action is taken. Fig. 2 shows the procedure occurring on every twenty-fourth J interrupt, i.e. every 120 milliseconds. Counters JTIM and INCTIM are incremented to show elapsed time and if AC # V is not set the value in cell EIST is subtracted from JTIM (EIST holds the value which was present in JTIM when an E level was performed three times ago). The result is compared with 5À4 sees. If it is less it is compared with 3À0 sees. and if less processing work proceeds. If EIST is more than 5À4 sees. AC#V is set. If AC#V is set the difference between JTIM and E3RD is calculated (E3RD being the level of JTIM at the last prior E-level visit). The elapsed time is compared with 8 seconds and if it is greater an emergency phase is commenced. The Specification includes a flow path (Fig. 3, not shown) for updating the values of EIST and E3RD and a flow path for altering the access rate to the D-level buffer (Figs. 4A, 4B, not shown).
