FUNCTIONAL DESCRIPTION
The SD1010D has the following major function blocks:
1. Input mode detection
2. Buffer memory and read/write control block
3. Image scaling, interpolation and dithering block
4. OSD mixer and LCD interface block
5. EEPROM interface block
6. CPU interface block
The following sections will describe the functionality of these blocks.
Input mode detection
i)
Supported input modes
SD1010D can handle up to 14 different input modes. For SD1010D, an input mode is defined
by its horizontal resolution with its vertical resolution. The input modes with the same
horizontal and vertical resolution but with different frame rates are still considered as one single
input mode. In the default EEPROM setup, SD1010D accepts the following seven input video
modes:
1. 640 x 350
2. 640 x 400
3. 720 x 400
4. 640 x 480 (VGA)
5. 800 x 600 (SVGA)
6. 832 x 624 (MAC)
7. 1024 x 768 (XGA)
Users can easily change the definitions of the acceptable input modes by adjusting the values in
the appropriate EEPROM entries. There is no frame rate restriction on the input modes.
However, since the output signal is synchronized with the input signal at the same refresh rate,
the input refresh rate has to be within the acceptable range of the LCD panel.
The user-defined video modes can be defined by storing appropriate timing information in the
EEPROM. Detail definitions of the EEPROM entries are described in Section 3.5.2.
