Video Image Processing System

The image size of the detector captures the size of the 1024*720,VGA display to be 1024x768, so a black background of 48 rows is added in the vertical direction.

The image captured by the detector is 30 frames per second

VGA display shows images of 60 frames per second

Read fast write slow, so there will be more than one time to read the same data situation.

Data written to SDRAM is first deposited into the write FIFO, and the data read from SDRAM is first stored in the read FIFO

When the amount of data in the write FIFO is greater than an SDRAM burst length, the SDRAM write command is generated

When the amount of data in the read FIFO is less than one SDRAM burst length, the SDRAM read command is generated

Write priority.
