    • A speaker unit in which an open end of each of acoustic tubes is disposed on an upper surface of a casing is produced. The speaker unit is mounted outside a seat, for example, to an upper position of a backface side of a backrest of the seat via a connecting member or the like. Thereby, the open ends of the acoustic tubes are disposed at a position near both ears of a seated person. Since low-frequency sound can be reproduced to an area near both the ears of the seated person, so much output sound pressure level of the drive speaker is not needed. Therefore, a drive speaker of a small bore diameter can be applied to the speaker unit, and the speaker unit itself can be made compact and light. The speaker unit is mounted on the backface side of the backrest of the seat, for example, and it is not necessary to take the trouble to ensure a place for placing the speaker unit around the seat. Accordingly, for example, when the speaker unit is mounted outside the seat of a vehicle, a narrow space inside the vehicle can be utilized effectively.
    • 制造声音管的开口端设置在壳体的上表面上的扬声器单元。 扬声器单元例如通过连接构件等安装在座椅的外侧到座椅靠背的背面侧的上部位置。 由此,声管的开放端设置在就座人的两耳附近的位置。 由于可以将低频声音再现到就座人的耳朵附近的区域,所以不需要驱动扬声器的输出声压级。 因此,可以将扬声器单元施加小孔直径的驱动扬声器,并且可以使扬声器单元本身紧凑且轻便。 例如,扬声器单元安装在座椅的靠背的背面侧,并且不需要麻烦以确保将扬声器单元放置在座椅周围的位置。 因此,例如,当扬声器单元安装在车辆的座椅的外部时,可以有效地利用车辆内的狭窄空间。

    • An information transmission/reception system includes a radio paging data transmitter equipped with a data segmentation block which segments transmission data into transmission data segmentation units to obtain data segments, and an information identification number addition block which adds a plurality of pieces of identification information to each data segment in order to identify the transmission data. A sequence information addition block adds sequence information to each data segment in the sequence in which it is segmented, and a transmission processing block which performs transmission processing so that data segments to which different identification information is added are assigned within a single data transmission cycle. A radio paging data receiver of the information transmission/reception system is equipped with an information identification number discrimination block which performs the discrimination of data segments from the information identification number. The receiver further includes a data restoration block which restores the data segments for each identification information number stored in a memory based on the sequence information.
    • 信息发送/接收系统包括:无线电寻呼数据发射机,其配备有将发送数据分割成发送数据分割单元以获得数据段的数据分段块;以及信息识别号码相加块,其将多条识别信息添加到每个 数据段以便识别传输数据。 序列信息添加块将序列信息添加到其被分割的序列中的每个数据段,以及传输处理块,其执行发送处理,使得在单个数据传输周期内分配不同的标识信息的数据段。 信息发送/接收系统的无线寻呼数据接收机配备有从信息识别号码执行数据段的鉴别的信息识别号码识别块。 接收机还包括数据恢复块,其基于序列信息恢复存储在存储器中的每个识别信息号的数据段。

    • Texture data containing pixel data indicating the color of a plurality of pixels arrayed in matrix fashion are stored in a texture buffer of a DRAM, and the multiple pixel data stored in the texture buffer is simultaneously accessed using a two-dimensional address (U, V) corresponding to the two-dimensional array of the plurality of pixels. The texture buffer stipulates unit blocks containing multiple pixel data to be simultaneously accessed, and stores a plurality of unit blocks making up texture data so as to be continuously positioned within a one-dimensional address space. Accordingly, the storage area of the texture buffer can be used efficiently, and further, simultaneous processing of image data of multiple pixels can be realized.
    • 包含表示以矩阵方式排列的多个像素的颜色的像素数据的纹理数据被存储在DRAM的纹理缓冲器中,并且使用二维地址(U,V)同时访问存储在纹理缓冲器中的多个像素数据 )对应于多个像素的二维阵列。 纹理缓冲器规定了包含要同时访问的多个像素数据的单位块,并且存储构成纹理数据的多个单位块,以便连续地位于一维地址空间内。 因此,可以有效地利用纹理缓冲器的存储区域,并且可以实现多个像素的图像数据的同时处理。

    • Texture data which is two-dimensional image data indicating color data of multiple pixels positioned in a matrix form is stored in a texture buffer of a DRAM, a texture engine circuit combines the bit data making up the U address of a two-dimensional address (U, V) represented by n bits (wherein n is an integer of 1 or greater) and the bit data making up the V address of the two-dimensional address (U, V) represented by m bits (wherein m is an integer of 1 or greater), thereby generating an (n+m)-bit one-dimensional address, and the generated one-dimensional address is used to access the storage circuit. Accordingly, the storage area of the texture buffer can be used efficiently with a small circuit configuration.
    • 作为表示以矩阵形式定位的多个像素的颜色数据的二维图像数据的纹理数据存储在DRAM的纹理缓冲器中,纹理引擎电路组合构成二维地址的U地址的位数据( U,V),由n位表示(其中n是1以上的整数),构成由m位表示的二维地址(U,V)的V地址的位数据(其中,m为 1或更大),从而产生(n + m)位一维地址,并且所生成的一维地址用于访问存储电路。 因此,可以以小的电路配置有效地使用纹理缓冲器的存储区域。
