    摘要: In a video-type computer system and the like, an improved memory circuit is provided for adapting the system to CRT screens having different resolutions. The memory circuit includes a bit-mapped RAM unit or chip having sufficient cells to accommodate any CRT screen sought to be used, and also a serial shift register having taps at a plurality of different locations corresponding to different columns of cells in the RAM unit. When the RAM unit is in serial mode, a row of data is transferred into the serial shift register. Then the column address applied to the RAM unit is used to instruct and actuate a suitable decoder circuit to select the tap appropriate to unload the portion of the serial shift register containing the data bits of interest.

    摘要: In a computer system, an improved memory circuit is provided for accomodating video display circuits with CRT screens having different resolutions. The memory circuit includes a bit-mapped RAM unit or chip having sufficient cells to accomodate any CRT screen intended to be used, and it further includes a serial shift register having a plurality of taps at locations corresponding to different preselected columns of cells in the chip. In the system, provision is included for selecting taps to unload only the portion of the shift register containing the bits of interest, whereby unused portions of the chip may be effectively excluded and the time for transferring data of interest to the CRT screen is reduced.

    摘要: A semiconductor memory circuit includes memory arrays (10), (12), (14) and (16). Each of the memory arrays has associated therewith shift registers (34), (36), (38) and (40). Transfer gates (54) are disposed between the memory arrays and the associated shift registers. A control circuit (69) is provided for receiving an external transfer signal and transferring the data between the arrays and the associated shift registers. The shift registers are clocked in response to receiving an external shift clock signal to serially output data therefrom. A delay circuit (292) is provided for delaying shifting of data for a predetermined duration to ensure that a complete transfer of data has been effected. Transfer of data is inhibited until the occurrence of the XBOOT signal by circuit (296) to provide for early occurrence of the transfer signal. Data access is maintained by a delay circuit (330) to accommodate late occurrence of the transfer signal by delaying the internal row address strobe.

    摘要: In a video computer system having a RAM chip with a shift register connected to its serial output terminal and actuated by a first clock circuit, a second different clock circuit is included to cause the data bit in the first stage of the register to also appear at the serial output terminal of the chip. Accordingly, signals from the first clock circuit will then sequentially transfer data bits from the shift register, to the output terminal of the RAM chip, without omitting or losing a clock cycle, or a portion thereof.

    摘要: A single-chip microprocessor device of the MOS/LSI type contains an ALU, internal busses, address/data registers, an instruction register, and control decode or microcontrol generator circuitry. The device communicates with external memory and peripherals by control lines and a bidirectional multiplexed address/data bus. In addition to the main off-chip memory, a smaller on-chip memory (including both ROM and RAM not in the main off-chip memory map) is provided which allows execution of instruction sequences to emulate complex instructions or interpretors (macro-instructions). The macro-instructions are indistinguishable from "native" instructions since all memory fetches and the like are generated exactly the same way, and long instruction sequences are interruptable. Also, off-chip access of another memory separate from the main memory allows emulator functions or special instructions.

    摘要: The graphics data processor of the present invention offers as a single instruction in its instruction set a draw and advance operation. A first data register stores a set of X and Y coordinates. In a first embodiment, a predetermined color code is stored at the pixel address of a bit mapped display memory indicated by the X and Y coordinates the first data register upon execution of the the draw and advance instruction. The X and Y coordinates stored in the first data register are then advanced by addition of X and Y coordinates stored in a second data register. A second embodiment is similar except that the color code stored at the X and Y coordinates of the first date register is recalled for combining with the predetermined color code and the combined result stored at that pixel location. The predetermined color code is preferrably stored in another data register. By proper selection of the X and Y coordinate data stored in the second data register either the X or the Y coordinate may be altered alone or both may by simultaneously changed. Provision of signed X and Y coordinate values in the second register enables either the X or Y coordinate to be incremented of decremented. This instruction serves to inhance the speed at which a line or computed curve may by drawn in the bit mapped display.

    摘要: The present invention presents a process of moving an array of pixel data representing an image to be displayed from a source memory space to a destination memory space. The array of pixel data is arranged in words containing a plurality of individual pixel datum. The process includes transforming each pixel datum in the word fetched from the source memory space to a colorized pixel datum by individually attaching color information to each pixel datum. The transforming occurs substantially in parallel on all of the pixel data in each word. This technique permits storage of commonly used images such as alphanumeric characters of various fonts or icons in a compressed form with one bit per pixel. These images are formed in color using the color expand operation at the time of drawing into the color display memory. Otherwise these images would need to be stored in multiple bit per pixel color form for all desired colors requiring considerable memory for redundant data. This color expanded image may then be combined with the color image stored in a selected part of the display memory and the combined image stored in that selected part of the display memory. Thus monochrome images may be expanded into color images and then combined with color images already in the display in a single operation.
