Google SkyWater IC-manufacturing project

Anyone else see this? Did you ever dream about creating your own chip? I mean, a physical chip. One which you can hold in your hand, and which does exactly what you’ve designed it to do? Until today, there were two major road blocks: you had to get access to a process design kit (PDK) from a chip ma...

Re: My summer project: A colour Stacy

Of course, bear in mind that all of this part of the project may go away, depending on how well @Smonson's RGB or HDMI board can be made to work in here. How much room do you have to work with? The HDMI board made by Icky is getting ridiculously small these days, it might be the easiest fit once it...

How about two of these? https://au.mouser.com/ProductDetail/ISS ... VRZQ%3D%3D

I guess you will need 3x 24-bit buffers in total. Two one line in length for the scandoubler functionality, and one giant one to hold the previous field for the deinterlacer.

Re: Sidequest: VGA scan doubler

Re: Sidequest: VGA scan doubler

The reason I've used 2 ram chips - even though 1 would have been more than enough to hold the amount of data - is because at the pixel clock they're working at the full 32MHz. So I have one dedicated to reading and one dedicated to writing, and then switch RAMs at the end of each scanline. Otherwise...

But memory access... DDR3 AXI4 is complex! What memory are you using?
