35.2.2. Parameters
Parameter Name | Description |
---|---|
Horizontal Sync Pulse Pixels | The width of the h-sync pulse in number of pixels. |
Total Vertical Scan Lines | The total number of lines in one video frame. The value is the sum of the following parameters: Number of Rows, Vertical Blank Lines, and Vertical Front Porch Lines. |
Number of Rows | The number of active scan lines in each video frame. |
Horizontal Sync Pulse Polarity | The polarity of the h-sync pulse; 0 = active low and 1 = active high. |
Horizontal Front Porch Pixels | The number of blanking pixels that follow the active pixels. During this period, there is no data flow from the Avalon® -ST sink port to the LCD output data port. |
Vertical Sync Pulse Polarity | The polarity of the v-sync pulse; 0 = active low and 1 = active high. |
Vertical Sync Pulse Lines | The width of the v-sync pulse in number of lines. |
Vertical Front Porch Lines | The number of blanking lines that follow the active lines. During this period, there is no data flow from the Avalon® -ST sink port to the LCD output data port. |
Number of Columns | The number of active pixels in each line. |
Horizontal Blank Pixels | The number of blanking pixels that precede the active pixels. During this period, there is no data flow from the Avalon® -ST sink port to the LCD output data port. |
Total Horizontal Scan Pixels | The total number of pixels in one line. The value is the sum of the following parameters: Number of Columns, Horizontal Blank Pixel, and Horizontal Front Porch Pixels. |
bits Per Pixel | The number of bits required to transfer one pixel. Valid values are 1 and 3. This parameter, when multiplied by Data Stream Bit Width must be equal to the total number of bits in one pixel. This parameter affects the operating clock frequency, as shown in the following equation:
Operating clock frequency = (bits per pixel) * (Pixel_rate), where Pixel_rate (in MHz) = ((Total Horizontal Scan Pixels) * (Total Vertical Scan Lines) * (Display refresh rate in Hz))/1000000. |
Vertical Blank Lines | The number of blanking lines that proceed the active lines. During this period, there is no data flow from the Avalon® -ST sink port to the LCD output data port. |
Data Stream Bit Width | The width of the inbound and outbound data. |
