A data processing system including: a memory controller; and a memory connected to said memory controller; wherein said memory controller includes a rendering circuit thereby to execute a rendering command generating display data based on graphic data provided after processing a program in a CPU, and stores said display data in said memory.

Graphic processing apparatus and method

A graphic processing apparatus for generating, display or printing characters and graphic data. A successive column access is used in which a row address is designated for access to a memory and data in different column address within the designated same row address are successively accessed and buffer means for buffering a series of data between an access by a processor and an access to a memory is provided. A program and image information for display are stored in a main memory. A frame buffer and the main memory are integrally configured simply and small in size.

A display device has a touch pad and a display lamintated together to form a screen, That screen is connected to a controller which processes signals generated by physical contact with the touch pad and activates the display to display e.g. characters input by a stylus to the touch pad. The display device is connected to an external device (e.g. a computer) and video signals from the external device are received via a video input and may be displayed on the display. Also the controller can transmit to the external device via an output. Thus, the display can display simultaneously information from the external device and information input to the touch pad. If the controller is arranged to carry out character recognition, the display device may then act as a hand-writing input device, with the handwritten information being incorporated with information in the external device and displayed.

Display device and display system incorporating such a device

The present invention relates to a multi-user pattern data processing system configured for various kinds of patterns, such as characters, to learn efficiently and effectively. The present invention comprises an input arrangement 1 having patterns entered therein from a plurality of users, a dictionary 2 having patterns and attributes of the patterns belonging thereto defined therein, a recognizing arrangement 4 that receives the entered pattern and a group attribute and retrieves from among the patterns entered in the dictionary and having a corresponding group attribute to feed out the category, and a dictionary editing arrangement 5 for extracting a pattern used in common by a group before editing the pattern, such as entering it in the common dictionary, with the group having the user made to belong thereto. The invention allows the dictionary used to the pattern recognition to learn very efficiently and effectively.

Collaborative learning system and pattern recognition method

The present invention relates to an information processing system using a coordinate detection device and displays, and more specifically to an input-display integrated information processing system which allows the displays to be carried like paper and to be freely laid out and stacked together on a desk (coordinate input device). The system includes a layout determining unit for determining a layout of the display on said coordinate detection device, wherein the layout determining unit further comprises a display position coordinate detector that detects where in the coordinate space of the coordinate detection device the display for displaying an information is located, and a coordinate converter that converts the information into display coordinates. The layout determination is done by using markers attached to three of the four corners of the display.

Information processing system

A rendering processor having a plurality of DDA control circuits such that in each DDA circuit, the coordinates of source and destination images and gradation values are computed. Depending on the computation result, source and destination data to the raster arithmetic unit are generated so as to control the raster arithmetic unit, which enables a plurality of pixels to be generated and to be written in the memory during a memory access.

An image composing and displaying apparatus includes frame memory constituent elements of an identical structure, a video input section, a video output section, a controller for selecting connection of each element to the video input or output section, and an image drawing section for reading and writing video data from and in the elements. The memory elements can be used for the input and output operations and hence the size thereof can be easily expanded; moreover, the numbers of the elements respectively connected to the video input and output sections can be adaptively varied.
