    Abstract: The output of a butterfly unit is entered into a product-sum unit in a forward DCT and the output of the product-sum unit is entered into the butterfly unit in an inverse DCT. The product-sum unit employs, as a bit-string distribution circuit, a register circuit having eight bit shift registers each having a 16-bit parallel input and a 2-bit shift output and the bit shift registers are different in bit width from one another. Data are entered into the bit shift registers with the largest bit-width bit shift register first, such that the respective bit shift registers are shifted rightward by 2 bits per cycle. Four shift registers are disposed between the bit-string distribution circuit and a RAG circuit such that, when bit strings are entered, as delayed cycle by cycle, into eight RAGs of the RAC circuit, the final accumulation results are successively provided from the RACs in a proper order. This reduces the bi-directional DCT processor in circuit arrangement.

    Abstract: There is provided an image forming system that are capable of preventing a user or operator from forgetting to carry out a maintenance operation based on required sub-maintenance items after execution of a maintenance operation based on an associated maintenance item, such as component replacement, cleaning, or adjustment. A table of maintenance items and sub-maintenance items associated with respective ones of the maintenance items is stored in a ROM. When a CPU determines that a maintenance operation based on a selected one of the maintenance items has been completed, the CPU determines whether or not there is any sub-maintenance item associated with the selected maintenance item, by referring to the table. When it is determined that there is one or more sub-maintenance items associated with the selected maintenance item, a CPU provides control to display the sub-maintenance item or items in an operating/display unit.

    Abstract: This invention provides an image forming apparatus capable of shortening the user's print waiting time as much as possible when it is determined that image adjustment is necessary during the image forming operation, and a control method therefor. To accomplish this, in a color image forming apparatus including a plurality of image forming stations which form toner images with a plurality of toners on the basis of a job, it is discriminated whether adjustment processing is necessary during a continuous image forming operation based on the job. If it is discriminated that adjustment processing is necessary, it is determined whether each of the image forming stations has a non-operating time enough to execute the discriminated adjustment processing during the image forming operation. The image forming station determined to have a non-operating time enough to execute adjustment processing executes the discriminated adjustment processing during the non-operating time.
