    • An apparatus for parallelly processing image data from a local image data source, in which m rows x n columns of image data are processed by simultaneously processing n image data for each of the m rows (m and n being integers). The apparatus includes a member for serially receiving image data, a memory section having processing parameter data stored therein, a plurality of juxtaposed processor stages coupled to the memory section and arranged to be simultaneously supplied with sequentially shifted image data to thereby simultaneously produce processing results from the supplied image data and the processing parameter data, and an output section for receiving the outputs of the processor stages and delivering a processed output. The processing apparatus is suitable to be implemented in an IC form.
    • 一种用于从本地图像数据源并行处理图像数据的装置,其中通过同时处理m行(m和n为整数)的n个图像数据来处理m行×n列的图像数据。 该装置包括用于串行接收图像数据的部件,具有存储在其中的处理参数数据的存储器部分,多个并置的处理器级,其耦合到存储器部分,并被布置成同时提供顺序移位的图像数据,从而同时产生 所提供的图像数据和处理参数数据,以及输出部分,用于接收处理器级的输出并传送经处理的输出。 该处理装置适于以IC形式实现。

    • In a graphic processing system, there are provided a main memory, a buffer containing a bit map memory for holding display data, a central processing unit for performing a data process involving a translation from a virtual address into a physical address so as to access the main memory, a graphic processor connected to the main memory and buffer, for processing data into a display form, and a system bus interface connected to the central processing unit, main memory and graphic processor, capable of exchanging the data among them. Furthermore, the graphic processing system includes a drawing processing unit connected to the system bus interface, for translating the virtual address into the physical address so as to access the main memory and to process the data, a bus arbitrator for performing arbitration between demands for using the interface given from the central processing unit and graphic processor, and a suspend circuit for asserting a signal requesting that the interface is released to the central processing unit.
