Abstract: PROBLEM TO BE SOLVED: To smoothly switch between a wire connection and a wireless connection, when a system is equipped with a wire connection channel and with a wireless connection channel between the system and a terminal. SOLUTION: Communication between a display device 50 and an arithmetic processing unit (host) 10 is provided with two connection modes, a wire connection mode for communication via the wire connection channel 20 and a wireless connection mode for communication via the wireless connection channel 30. Before entering the wireless connection mode, the processing unit (host) 10 sends out information needed for the wireless connection from/to the display device 50 via the connection channel 30 and information necessary for authentication for allowing access of information, using the connection channel 30 to the display device 50 via the connection channel 20.

Abstract: PURPOSE: To reduce the capacity of a frame buffer required in the case of executing both super-sampling and double buffering. CONSTITUTION: This system uses a frame buffer 15 provided with one set of a plurality of sub pixel storage positions for each pixel and two display storage positions. A filtering result of a content for one set of a plurality of the sub pixel storage positions is stored in the display storage position and the content of the other display storage position is displayed on a display device. It is discriminated which of the display storage positions reflects the content of one set of a plurality of the sub pixel storage positions by setting an event as to whether or not the filtering result is identical to the content of the display storage position to a control bit, and then the required capacity of the frame buffer 15 is not doubled even when double buffering is conducted. Double buffering is conducted by selecting either of the two display storage positions.

Abstract: PURPOSE: To make moving machines mounting active sensors using the same energy wave coexist closely to each other. CONSTITUTION: The moving machine enters an exclusive transmission mode with respect to the transmission of an energy wave when interference can occur between its active sensor and those of other moving machines. Before transmitting the energy wave, the moving machine judges whether or not a competitive moving machine has acquires a energy wave transmitting right (121). When the competitive moving machine has not acquired the transmitting right, the traveling machine broadcasts the declaration of the acquirement of the energy wave transmitting right (122) and transmits the energy wave (123). When the competitive machine has acquired the right, the machine joins a transmission queue (125) and, whenever machine receives the declaration of the waiver of the energy wave transmitting right from other moving machines, the machine increases its priority in the queue.

Abstract: PROBLEM TO BE SOLVED: To draw out the performance of a whole system as much as possible by detecting the increase/decrease of a feature variable in a quene for transmitting/receiving processed results between plural groups and changing the allotment of processing in the respective groups based on the increase/ decrease of the feature variable. SOLUTION: A processing allotment controller 11 monitors command queues 1 (7), 2 (9) and detects the increase/decrease of a feature variable to be an index in the case of changing the processing allotment. When the feature variable of the command quene 1 (7) is reduced to more than a prescribed threshold, the controller 11 instructs a processor group 1 (1) to execute only a process 0 and instructs a processor group 2 (3) also to execute a process 1. When the feature variable of the command queue 2 (9) is reduced to more than the prescribed threshold, the allotment processes are adjusted between both processor groups 2 (3) and 3 (5).

Abstract: PROBLEM TO BE SOLVED: To transmit picture information with high resolution even with the small band width of a transmission path by transmitting information of respective pixels in each block in order of the values of corresponding matrix elements in a dither matrix. SOLUTION: CPU 7 executes a processing by using a main memory 9. A plotting instruction is outputted to a plotting controller 11 at the time of plotting in the display 27 of a monitor 3. The plotting controller 11 reads required data from a frame memory 1(15) and writes data in the frame memory 1(15). A transfer controller 19 outputs data of the pixel in the frame memory 1(15) to the monitor 3 with a transmission path 5. In this case, a dirty bit memory 17 is referred. Then, the plural pixels in the frame memory 1(15) are divided into the plural blocks by the size of the dither matrix and corresponding pixel data are transmitted in order of the values of the matrix elements of the dither matrix in the blocks.

Abstract: PURPOSE: To parallelly perform processing in multiple processors by quickly utilizing a TSL snapshot at an optional point of time and making a graphic system to efficiently allocate a plotting instruction to respective nodes. CONSTITUTION: When an attribute setting instruction is sent out, it is written in a first TSL buffer first. At the time, a difference between the corresponding addresses of first and second TSL buffers is obtained by a comparator circuit and a change part is stored by a TAG circuit. In the meantime, when a primitive is allocated, the contents of the TAG circuit is referred to and copying is performed from the first TSL buffer to the second TSL buffer only for the change part. Then, the second TSL buffer is locked and the instantaneous value of the TSL is held. An MPU performs a plotting processing while referring to the snapshot of the TSL held by the second TSL buffer.

Abstract: PURPOSE: To efficiently execute the function of texture mapping by providing plural plotting processors which are respectively connected to one of plural texture memory clusters and generate data to be displayed in a pixel through the use of a texture value ax against the pixel. CONSTITUTION: When a certain kind of display is executed in a display device 11, plotting is instructed to a graphic sub-system 3, a geometry calculating part 5 executes polygon-division, a coordinate on a screen at the vertex of a polygon is obtained and the coordinate of a texture image in the coordinate is calculated. When color is designated, moreover, the color information is also calculated and a luster calculating part 7 calculates the coordinate on the screen and the coordinate of the texture image at every pixel inside the polygon. A texture calculating part 9 generates the texture value against the pixel from the coordinate of the texture image and the magnifying/reducing rate LOD of the pixel.
