摘要： A data processing apparatus includes physical registers larger in number than logical registers specified by a register specification field of an instruction executed by the apparatus. The physical registers are classified into a plurality of banks. In response to a particular instruction, an execution control section supplies a register address converter with bank information to select a bank of the physical register. The converter stores the bank information in a bank register. Receiving logical register address information specified by the register specification field of the instruction, the address converter adds the bank information set to the bank register to at least a portion of the logical register address information, thereby producing a physical register address which can specify any one of the physical registers.

摘要： In an image displaying field where there is a tendency which will increase the data to be handled in accordance with the high integration of a display device, a CRT controller according to the present invention improves the superposed display and the responsiveness of the display and drawing operations by dividing a unit clock into a predetermined number to function with high speed and a multifunction display. When image data are to be inputted to or outputted from a refresh memory corresponding to a display frame, the memory content and the display address are assigned at a ratio of 1:n to effect the processings in parallel. As a result, the time period utilized by the display cycle of the prior art can be assigned to the drawing operation so that the processing can be speeded up while making it easier than the prior art to effect the superposed display of letters, symbols and drawings. The resultant effect is that it is unnecessary to increase the number of refresh memories corresponding to the displayed frame and that the external parts can be simplified to contribute to the improvement in the reliability.

摘要： A high-speed memory employing the pipeline technique is disclosed, in which the minimum operating cycle time is reduced by use of a latch circuit for a small signal using a bipolar transistor. A small-signal latch circuit operating at a signal smaller than an output signal level is inserted between an amplifier circuit for amplifying the data held in a memory cell circuit and an output buffer circuit. A switch signal is also interposed between the latch circuit and the amplifier circuit, thereby shortening the cycle time.

摘要： A graphic processor which controls reading, writing and transfer of graphic data for a display memory that stores graphic data. The processor includes a first unit which stores first address information for addressing the display memory and first pixel address information which points a pixel position in a word specified by the first address information, a second unit which stores second address information for addressing the display memory and second pixel address information which points a pixel position in a word specified by the second address information, a third unit which shifts graphic data of multiple pixels included in two consecutive words to extract continuous 1-word graphic data, and a fourth unit which implements drawing computations pixel-wise concurrently for one word depending on the number of pixels included in a word. Even if transfer source graphic data lies across two consecutive words, the processor fetches the source data in single reading, processes the data word-wise at once, and stores the result in the display memory.

摘要： A CRT (cathode ray tube) controller for controlling one CRT device in an interlace mode has a synchronizing circuit of bi-directional construction, in order to make possible synchronous operation of the CRT controller with other circuits (other CRT controllers or a TV system). When the CRTC is used as a master circuit of a CRT display system, a synchronizing signal is derived from the synchronizing circuit in synchronization with a count signal of a vertical scanning counter and an output of an interlace controller of the CRTC, and is supplied to a synchronizing terminal of the other CRTCs. Scanning counters and a flip-flop for controlling an interlace operation of the other CRTCs are reset to their initial state in synchronization with the synchronizing signal. When the CRTC is used as a slave circuit, scanning counters and a flip-flop of the CRTC are reset to their initial state in synchronization with the external synchronizing signal.

摘要： The invention relates to a digital data processor based upon the pipeline control system, which is particularly effective when the time required for reading a microprogram is relatively short. A microcycle is based upon the time required for reading the microprogram, and the operations on the data is executed in a pipeline system by dividing it up according to the determined microcycle. This is done by providing a destination latch register on the output side of the arithmetic unit. The invention further deals with the processors in which the destination latch register is provided on the input side of the arithmetic unit, or when the destination latch register is incorporated within the arithmetic unit, and a circuit setup for avoiding any contention for a register that may develop when executing a current instruction and the next instruction is provided in accordance with an added microprogram.
