Title: Data stores
IPC: G11C11/06
Filed: 1970-11-13
Abstract: 1316290 Digital storage systems INTERNATIONAL BUSINESS MACHINES CORP 13 Nov 1970 [19 Dec 1969] 54007/70 Heading G4C  A store has a capacity of p.q words each of r bits and is so arranged that reading and/or writing of at least 2 words can take place simultaneously. In the embodiment described the store 1, Fig. 1, comprises a stack of r planes each containing p.q. cores defined by X and Y co-ordinates. The Z co-ordinate defines a complete r-bit word. Each core is associated with three wires, X, Y, Z. X, Y and Z drivers 2, 3, 4 and X and Y sense amplifiers/bit drivers 5 are available to each core. A required core is accessed by driving the appropriate Z driver and an appropriate one of the X or Y drivers. In the embodiment the store is associated with separate subsystems A, B, e.g. a central processor and an input/output subsystem. Fourbit addresses supplied by the subsystems are stored in respective address registers 8, 9 and indicate the two word locations to be simultaneously accessed. The registers feed X, Y and Z decoders 10, 11, 12, which supply signals to drivers and gates causing data to be read out from or read in to the store via input/output register 6, 7. During a reading operation, if the words to be read are in the same X row the X preamplifiers connected to the relevant two Y wires will be connected to the sense amplifiers. If the words are in the same Y column the Y preamplifiers will be connected to the sense amplifiers. If the words do not lie in the same row or column either the X or the Y wires will be connected to the sense amplifiers via the Y or the X preamplifiers. In each case the two appropriate Z drivers are activated. The sense amplifiers/bit drivers 5 pass the words to/from the input/output registers 6, 7 under the control of a selector circuit controlled by the addresses in the address registers 8, 9. The storage system may be modified, Fig. 3A (not shown), to allow a third equipment, e.g. a microprogram device, to access the store by assigning the microprogram either to subsystem A or B and then assigning either the input/output system or the central processing unit to the other sub-system. More than two words may be accessed by provision of an additional core wire for each additional word.

Abstract: 1,176,520. Radar. CONSUMERS ASSOCIATION, G. M. HUGHES, and M. A. REDDAWAY. 8 Nov., 1968 [4 Dec., 1967], No. 55111/67. Heading H4D. Vehicle testing apparatus comprises a Doppler radar 10, 12 affording an output Doppler signal representative of the velocity of the vehicle under test, means 13 providing a reference signal of frequency corresponding to that of the Doppler signal associated with a predetermined vehicle velocity, means responsive to the cycles of the output Doppler signal and the reference signal to effect a count.of the number of excess cycles of one signal of those of the other, means for comparing the frequency of the output Doppler signal with that of the reference signal to start the count when the compared frequencies are substantially equal and means for determining the time taken for the count to reach a predetermined value. The invention is used to determine the time needed to overtake a hypothetical vehicle travelling steadily at a predetermined speed. Each blocking oscillator 16, 17 produces for each input pulse a rectangular pulse and a spike pulse: if two input rectangular pulses overlap a detector 18 causes gates 22, 23 to close. The spike pulses are shaped, 19, 20, into pulses with a fast rise time and these are passed through gates 22, 23 when open to a subtraction system which includes a gate 25 closed by a control 24 and opened when a Doppler pulse appears at the output of gate 22. A reference channel pulse causes control 24 to close gate 25. The excess Doppler pulses are passed via a shaper 26 and a gate 32 to a counter 27. A binary counter 28 is started when the frequencies of the Doppler and reference signals are substantially equal; when counter 27 reaches the predetermined count it passes a a pulse to control unit 31 which then closes gates 30, 32: the number of timing pulses held by counter 28 represents the time for the overtaking of the hypothetical vehicle. A number of tests may be effected during one test run by feeding the radar output to a number of the above processing systems, each having a different frequency of oscillator 13.

Abstract: 1,196,259. Digital calculators; delay line stores. INTERNATIONAL BUSINESS MACHINES CORP. 13 Dec., 1967 [23 Dec., 1966], No. 56945/67. Headings G4A and G4C. Data processing apparatus comprises a delay line recirculating store, input means to enter data into a first of its time slots, and shifting means including a register connected in the loop to shift stored data along the sequence of time slots, the data items entering the register serially by bit, and means for reading each item of data from the register parallel by bit. A decimal number is entered high order first by pressing decimal digit keys on a keyboard, each digit being coded into BCD form by OR gates, stored in entry latches, then serialized by gates and entered into the recirculating delay loop. The delay loop comprises a magnetostrictive or sonic delay line capable of holding a field of ten digits, retiming triggers, and a one-digit shift register which is normally bypassed. Arrival of a digit in the entry latches causes digits already in the loop to be recirculated via the shift register for one revolution and the new digit to be inserted in front of them in the loop. The digits can be passed low order first, serially by digit, parallel by bit, from the shift register to an arithmetic unit to be used for updating fields in a main delay line. The keyboard includes a "double zero" key which causes two zeros to be entered, by delaying reset of the entry latches (which normally occurs after each digit) so that the same zero is entered into the delay loop twice.
