XilVGA
I'm making a VGA interface that can be controlled by an SPI protocol based on a Xilinx FPGA.
Introduction to the XilVGA project
Schematics for the XilVGA board
PCB design for the XilVGA board
The prototype board for the XilVGA
Initial tests of the XilVGA board
Reading from the on-board SRAM
Writing to the display
Starting work on the instruction set for the XilVGA
Making the board do something more useful
First step in adding accelerations to the XilVGA interface
Second steps in accelerating the interface
Getting coordinates into the board, and drawing lines
Fixing problems, and drawing circles
Preparing for fonts
Implementing the fonts on the XilVGA
PicoBlaze code for drawing lines
PicoBlaze source code for drawing circles
The last two are source code for the Bresenham line and circle drawing algorithms for PicoBlaze
