Standard VGA resolutions

• VGA: 640 x 480 pixels.
• **SVGA:** 800 x 600 pixels (also known as Super Video Graphics Array).
• **XGA:** 1024 x 768 pixels (Extended Graphics Array).
• **SXGA:** 1280 x 1024 pixels (Super Extended Graphics Array).
• **UXGA:** 1600 x 1200 pixels (Ultra Extended Graphics Array).

Take the resolution 640 x 480 for example:

1. Calculate the pixels in the frame:

   $\text{width} \times \text{height} = 640 \times 480 = 307200$

2. Assuming it is one bit per pixel:

   $307200 \times 1 \text{bit} = 307200 \text{bits}$

   Therefore, 307.2 KiloBits and 38.4 KiloBytes (or KB)

In order to store a binary bitmap frame buffer on our FPGA, we need to store 38.4 KB either on the FPGA silicon or on RAM or flash?

Main components of a VGA interface

There are a total of 6 important pins for a VGA interface (including ground):

• GND
• RED
• GREEN
