A multipolar resolver is so constructed that the need of the conventionally indispensable coil on the resolver rotor is eliminated by providing a center coil on a stator, and 5n or 3n rotor poles and 4n stator poles are provided where n is a positive integer. Sine and consine coils are wound on the stator poles alternately, thus simplifying the construction of the multipolar resolver.

A graphic system which includes a display device having a graphic display area which includes a plurality of display portions and a plurality of one-chip semiconductor integrated circuit devices. Each one-chip semiconductor integrated circuit includes memory for storing a plurality of pixel data, each pixel data includes a plurality of bits and color data, and a logic circuit for carrying out logic operation on a unit of one pixel data read out from the memory based on a function signal supplied to the one-chip semiconductor integrated circuit device. The function signal indicates a relation between the unit of one pixel data read out from the memory and pixel data output by the logic circuit. The invention further includes an external device for supplying the function signal to the one-chip semiconductor integrated circuit device. The logic circuits, of the plurality of one-chip semiconductor integrated circuit devices, each carry out the same logic operation in accordance with the function signal. Further the logic circuit of the one-chip semiconductor integrated circuit device outputs pixel data based on the logic operation carried out by the logic circuit so as to display the pixel data from the logic circuit on one of the display portions of the graphic display area of the display device.

A memory device formed on an IC chip includes dynamic random access memories for effecting data read and write operations, first and second data terminals for receiving data from an external side of the IC chip, and a controller having a first data input connected to the first data terminal to receive first data, a second input connected to receive second data read, a third data input connected to the second data terminal to receive a function mode signal, and operation unit for executing operations between the first data provided from the first data input and the second data provided from the second input. The operation unit includes a function setting unit responsive to the function mode signal for setting a function indicated by the function mode signal prior to receipt of the first data. The second data is read out of a selected part of the storage locations. The operation corresponding to the function set by the function setting unit is executed for the first and second data. The result of the execution is written into the selected part of the storage locations via the input of the dynamic random access memories during one memory cycle.
