    • A polygon drawing apparatus for drawing a polygon which is colored inside its outline by using outline data indicating the outline of the polygon, the apparatus comprising: an outline data generation unit for generating outline data indicating the outline of the polygon on the basis of coordinate data indicating the coordinates of points constituting the polygon; a mask data generation unit for performing, for a predetermined amount of the outline data, parallel exclusive-OR processes in units of amounts constituting the predetermined amount, thereby generating mask data which specifies “coloring” for the inside of the outline; and a segment generation unit for drawing the polygon by using the mask data generated by the mask data generation means. Therefore, this polygon drawing apparatus can provide a satisfactory result of display without using a bulk memory, and without increasing the processing load.
    • 一种多边形绘制装置,用于通过使用指示多边形轮廓的轮廓数据来绘制在其轮廓内着色的多边形,该装置包括:轮廓数据生成单元,用于基于坐标数据产生指示多边形轮廓的轮廓数据 表示构成多边形的点的坐标; 对于预定量的轮廓数据,以构成预定量的量为单位执行并行异或处理的掩模数据生成单元,从而生成对轮廓内部指定“着色”的掩模数据; 以及段生成单元,用于通过使用由掩模数据生成装置生成的掩码数据来绘制多边形。 因此,该多边形绘图装置可以提供令人满意的显示结果,而不需要使用大容量存储器,而不会增加处理负担。

    • An apparatus for receiving broadcasting signals includes a tuner for receiving a digital audio broadcasting signal, a channel decoder for obtaining information data based on the digital audio broadcasting signal received by the tuner, a source decoder for causing the information data obtained from the channel decoder to be subjected to a decoding processing to produce a digital audio signal and associated data accompanying the digital audio signal, a random access memory in which the associated data are stored and from which the associated data stored therein are read, and a control unit operative to store a selected part of the associated data obtained from the source decoder, which has predetermined quantity of data, in the random access memory, to read the selected part of the associated data stored in the random access memory therefrom and to extract a specific portion of the associated data from the selected part of the associated data read from the random access memory.
    • 一种用于接收广播信号的装置包括用于接收数字音频广播信号的调谐器,用于基于由调谐器接收的数字音频广播信号获得信息数据的信道解码器,用于使从信道解码器获得的信息数据 进行解码处理以产生伴随数字音频信号的数字音频信号和相关联的数据,随机存取存储器,其中存储相关联的数据,并且从其读取存储在其中的关联数据,以及控制单元,用于存储 在随机存取存储器中从源解码器获得的具有预定数量的数据的相关数据的选定部分从其中读取存储在随机存取存储器中的相关数据的所选部分,并提取出该部分的特定部分 来自随机存取存储器读取的相关数据的所选部分的关联数据。
