Abstract: A SIMD type processor includes a SIMD type arithmetic processing section which performs parallel processing by using a plurality of ALUs; and a global processor 102 that provides data to be arithmetically processed to a register and a data register group and provides the same instruction to each of the ALUs. Upon input of an interruption request for carrying out other parallel processing by interrupting a parallel processing currently carried out by the SIMD type arithmetic processing section, the global processor decides if the other parallel processing requested by the interruption request is to be carried out.

Abstract: To solve problems associated with undesirable duplication of see-through back image in a double-sided input document, a method of and a system for substantially eliminating the undesirable see-through back images initially scanns a front side image and a back side image from the double-sided document and store the scanned images. The front side image has portions, and some of the portions include an original front image as well as a see-through back image from the back side image. An edge amount for each of the portions is determined in the front side image. The see-through back images are separated from the original front images based upon the edge amount. To further improve the correct removal of the undesired see-through back image, the above processed portions having a certain edge are smoothed. Character portions and dot pattern portions are further separated from background portions in the smoothed data.

Abstract: A control device for controlling the drive of a stepping motor included in an electronic apparatus as a drive source is disclosed. The stepping motor is totally controlled by a microprocessor and driven by a motor driver. A memory stores control data for the acceleration, constant-speed drive and deceleration of the motor. A motor controller controls the motor via the motor driver with the control data loaded without the intermediary of the microprocessor. A constant-speed rotation end signal is input to the motor controller from either a CPU (Central Processing Unit) or an external unit as a repeat signal. When the repeat signal is "0", the control data stored in the memory and assigned to constant-speed drive is repeatedly loaded a preselected number or times, causing the motor to rotate at a constant speed. When the repeat signal is "1", the above control data is repeatedly loaded until the repeat signal changes to "0".
