Title: Integrated circuit arrangement
IPC: G06F1/04
Filed: 1973-03-22
Abstract: 1422469 Pocket calculators PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 March 1973 [25 March 1972] 13856/73 Heading G4A [Also in Division H3] In an integrated circuit having an electrical information input, logic gates and a clock C1 for controlling the logic gates, a connection for supplying power to the logic gates is controllable by SW for adjusting the current between a first value and a standby value in response to a control signal and the output frequency of the clock C1 is adjusted between one value and another together with the adjustment of the current in the supply connection between the first value and the standby value. The clock can be constructed so that its frequency varies with variations in the supply current. A detector can detect changes in current to the standby value and functions to control blocking of the output of the clock.  In the pocket calculator shown in Fig. 1, the energy source POW may be switched on to supply current to a liquid crystal, display DP. Control 5M connects low standby current via lines 1, 3 to a decoder DC and an arithmetic unit AR1, as a result the speed is limited in these components. When a button of the keyboard KB is depressed the first signal is obtained from a detector DT which actuates the control SW via an amplifier A and the decoder DC and the arithmetic unit AR1 are controlled by the first higher value of current via the lines 2 and 4. The decoding and calculating speeds are then higher. The control means SW can be controlled, e.g. for 0À5 sec. by the amplifier A, e.g. as long as the most necessary for an arithmetic operation. Alternatively the control of the control SW may be terminated by a signal from the arithmetic unit. If a digit, erase or decimal point button is depressed the activity of the calculator is only limited. This applies to a lesser extent to adding and subtracting. For multiplication, division and root extraction an extensive calculation program is required. Consequently it may be that the current is set to the first value only in response to a command from a few buttons. The arithmetic unit AR1 includes a clock C1 whose clock frequency is adapted to the processing speed which can be achieved in the remainder of that circuit. The elements DT, DC, ARI, A and SW can be in combined integrated form or a plurality of chips can be used.
