Data processing system

摘要

A data processing system capable of implementing at high speeds animating image generation processing and animating image display processing in synchronization with each other, thereby generating and displaying an animating image in a real time. The data processing system uses a given memory area of a storage unit as a screen buffer memory for storing an animating image data for each screen and is provided with an image processor for writing an animating image data for each screen in a screen buffer memory, an image display processor for reading the animating image data for from the screen buffer memory and for generating a display screen graphic signal to be supplied to a display unit and a hardware register circuit having a screen read-out control register corresponding to the animating image data for each screen of the screen buffer memory. The hardware register circuit updates data of the screen read-out control register in synchronization with each of a write operation of an animating image data from the image processor and a read operation of the animating image data to the image display processor. A delivery and a receipt of the data of the animating image data for each screen is carried out at high speeds between the image processor and the image display processor through the screen buffer memory storing the animating image data therefor by a control of the hardware register circuit.
