AM3358的图像帧率问题

The maximum resolution for the LCD controller is 2048 × 2048 pixels. The maximum frame rate is
determined by the image size in combination with the pixel clock rate.

请问AM3358的图像处理的最小分辨率和最高帧率是多少？

Tony Tang：

AM335x LCDC的时钟频率可以达到126MHz.

LCDC functional clock can be mux selected among DISPLAY PLL CLKOUTM2, CORE PLLCLKOUTM5 or PER PLLCLKOUTM2. Supports MAX pixel clock of ~126MHz, configure DISPLAY PLL for 600MHz.

#2. 按照帧频计算方法。帧频=126.5MHz/(1920x1080x1.3)约为47MHz。

max frame rate = PCLK / (X * Y * 1.3)

PCLK is the pixel clock rate
X is the resolution width
Y is the resolution height
1.3 an approximation factor related to blanking times

你要多小的分辨率？
