Abstract: In order to reduce degradation of the processing performance of the data processor due to use of a part of the main memory as a display frame buffer, when an access request to the memory 200 is generated from the CPU 310, the memory controller 400 holds it once, requests the display controller 560 to stop the access to the memory 200 which is in execution, when data to the access executed already is transferred from the memory 200, holds it, and transfers the access request from the CPU bus 310 which is held by the memory 200. When the access from the CPU bus 310 ends, the memory controller 400 restarts the access stopped in the display controller 560 and passes the held data to the display controller 560.

Abstract: There is provided a communications-type car navigation system including a vehicle-mounted terminal and a server. When transferring, to the terminal, the result of a route searching which the server has performed, the server transfers the data that will satisfy the requirements of a route guiding method which the user wishes. Also, the server transfers the route data that has been compressed. Concerning the map data as well, the server transfers only the necessary attributes thereof. Moreover, the following conditions allow the operability to be enhanced: the selection of a map transferring method and the route guiding method where the driving state has been taken into consideration, and the selection of a guiding unit which the user wishes.

Abstract: In a navigation system, display screen handling PG 2032 prepares hierarchically a plurality of operation screens to receive the setting from the operator, and changes the operation screen displayed on display 208 according to the content of the operation to operation button group 207 by the operator, the operation screen under the display, and said layered structure. Further, communication control PG 2032 controls cellular phone 30 through cellular phone IF 204 when it is necessary to receive the information from the information service center 10 in order to process according to the setting given by the operator through each of a series of operation screens displayed on display 208, and establishes the communication line between information service center 10 and this system. And, after information is received, the communication line is cut off.

Abstract: In order to assure that a plurality of circuits such as a CPU I/F circuit, a rendering circuit, a video input circuit and a display circuit, which are each required to always complete a processing within a prescribed time, are each assured the ability to make as many accesses to a memory as required to complete the processing within the prescribed time, it is necessary to arbitrate a contention for an access to the memory through an internal bus among the circuits by employing a bus control circuit wherein priority levels assigned to the circuits to make an access to the internal bus are dynamically changed by comparing degrees of access urgency among the circuits. In this way, circuits that each have to always complete theirs processing within a prescribed time are assured the ability to make as many accesses to the memory as required to complete the processing within the prescribed time even if a plurality of such circuits do exist.

Abstract: In a remote control apparatus, for achieving remote control of an on-vehicle equipment, in accordance with a request received from a terminal other than the on-vehicle equipment, wherein a request receiver portion 101 receives control content from a stationary-type terminal 301 or a portable-type terminal 302, thereby registering it into a control information DB 105, while corresponding it to ID information of a user thereof. Upon receipt of the ID information from the on-vehicle equipment 20, a control information transmitter portion 102 transmits the control information depending upon the control content, being registered in the control information DB 105 corresponding thereto, to the on-vehicle equipment 20. With this, the on-vehicle equipment 20 is controlled in accordance with the control content, which was received from the user in advance, remotely.

Abstract: A graphic processing system having a main memory for storing a program and information corresponding to pixels, a main processor for executing a program transferred from the main memory or from external to control the system, display/output devices for outputting graphic information attained by a control of pixels arranged in a plurality of dimensions, a frame buffer for storing information corresponding to pixels output to the display/output devices, and a graphic processor for receiving a command and parameter information from the main memory and/or the main processor, for generating character and graphic data in accordance with a predetermined processing procedure, and for performing a transfer control including an execution of a drawing processing to transfer generated data through first and second address buses and first and second data buses to the main memory and/or frame buffer.

Abstract: A communication system to which a method for charging a user based on the fact that the user got advertisement information from a base station and dropped in at a shop associated with the advertisement information can be applied and a method for calculating an advertisement fee. A server system has a communication section transmitting and receiving data via a network, a storage section storing advertisement information, a storage section storing information relating to a base station therein, and a storage section storing information about an advertiser as customer information. The system transmits advertisement information requested by an advertiser to distribute it to a base station specified by the advertiser and calculates an advertisement fee charged to the advertiser based on a customer history received from an exclusive device installed at the shop associated with the advertisement.

Abstract: In a data processor and a shading apparatus used in the data processor, the data processor selects an address based on the information of a memory or a translation look-aside buffer. Therefore, even when the same data are accessed, a different address at high speed is adopted according to the hardware, object to be processed, processing, etc. A plurality of geometric vectors are given as the parameters for the vertexes of a picture, the vectors are interpolated in the picture, and the luminance of each small area in the figure is calculated using the vectors generated by the interpolation. Therefore, a spotlight or highlight can be expressed with high accuracy and at high speed even when the amount of the hardware and the extent of the picture are small.
