Abstract: Systems, apparatuses, and methods for driving a split display with multiple display pipelines. Frames for driving a display are logically divided into portions, a first display pipeline drives a first portion of the display, and a second display pipeline drives a second portion of the display. To ensure synchronization between the two display pipelines, a repeat vertical blanking interval (VBI) signal is generated if either of the display pipelines has not already received the frame packet with configuration data for the next frame. When the repeat VBI signal is generated, both display pipelines will repeat processing of the current frame.

Abstract translation: 用多个显示管道驱动分割显示的系统，设备和方法。 用于驱动显示器的框架被逻辑地分为多个部分，第一显示管道驱动显示器的第一部分，第二显示管线驱动显示器的第二部分。 为了确保两个显示管道之间的同步，如果显示管道中的任一个还没有接收到具有下一帧的配置数据的帧分组，则生成重复垂直消隐间隔（VBI）信号。 当产生重复VBI信号时，两条显示管道将重复对当前帧的处理。
