摘要
针对高速图形显示系统的应用要求,设计了一种采用静态RAM的双帧存结构的高速图形显示系统,双帧存的逻辑控制和显示控制器由FPGA实现,基于该系统的双帧存结构,提出了一种实现图形叠加的新方法,该方法通过两幅图形数据分别写入不同帧存的方式,实现两幅图形的叠加.进一步提出了一种实现复杂图形分割成两部分分别生成显示的方法,该方法使图形处理器的图形处理性能加倍.
According to applications of high performance graphics display system, a graphics display system based on double static RAM（SRAM） is proposed. In this graphics system, the logic controlling of the double SRAM and display controller are realized by FPGA hardware. Based on double SRAM, a method of graphics overlay display is proposed, in which graphics data writes to two pairs of different video memory. In addition, a rendering and a display method of complex graphics by cutting graphics in two is also proposed; this method can double system bandwidth in the graphics system above mentioned.
