Hi,
I would like to confirm one thing regarding the contents of AM5728 TRM(rev.i).
According to the TRM15.2.3.6.3.1.1 Buffer Size, it is written the below.
For instance, an initiator that must handle only a single progressive frame-buffer in any orientation of:
• Up to 1920 × 1080 in YUV4:2:0
• Up to 1600 × 1200 in 16-bit RGB565
• Up to 800 × 600 in 32-bit ARGB
requires a line buffer of at least 15,360 bytes because:
• 4 × 1920 + 4 × 2960 = 15,360 bytes required for a 3-plane YUV4:2:0 frame of 1920 × 1080
• 4 × 1920 + 8 × 960 = 15,360 bytes required for a 2-plane YUV4:2:0 frame of 1920 × 1080
• 8 × 1600 = 12,800 bytes required for a 16-bit RGB565 frame of 1600 × 1200
• 8 × 800 = 6400 bytes required for a 32-bit ARGB frame of 800 × 600
and a line buffer of at least 30,720 bytes when using a simple ping-pong buffer scheme.
This is an example, isn't this? My customer is trying to rotate 1280 x 1024 size (32bit ARGB) display. This does not mean that the buffer size is not enough for my customer.?
Please advise me.
Best regards,
Michi
