Looking for a cheap solution for micro-VGA adapter

[dpsman]

Can someone please, point me to a cheaper solution than

?

I´d like something about 800x600 with just 16 colors.
No BGA chips allowed !!

Tks in advance

Re: Micro-VGA Adapter

Well i started a similar project two months ago,and planned to use a spartan3 chip for that .But is just vga and up to 256 colors .I'm curious to know if they implemented this thing as an asic .or a commun fpga or even a micro .but if you need the sources of the design that i started .I'm probably 75% done .I stopped the project ,Because my product was too costly in small quatities for such poor performance( ineeded to display photos). and using a more sofisticated FPGA sends the cost over the roof compaired with the price of complete PCs
There was perfect chip for this application .It was the E5 family of TRSICEND .
but triscend went belly up .I still have 100 pieces but not enough for the product i was planning .But i'm still interested .so if you know what product they have used for their design i'd like to know .
maybe a 50 or 100 mhz SILABS microcontroller could handle this requirements?

one more thing i don't agree on calling this vga because is only vga if you have 256 colors otherwise the color mapping is to you to define !

Re: Micro-VGA Adapter

Do you have a cost estimation about your design? (unit price in 100 production)
I mean, just the hardware cost excluding IP

Re: Micro-VGA Adapter

to do a nice design i wanted to use a VIRTEXII pro .because it has a CPU and fast I/O channels . The thing with xilinx is that for 100 pieces their part is about $110 so to put together a complete design it would be $175 .So that's what i mean i we see the value of an ITX board ,Some are now as low as $180 and these are comple PC architectures .I imagine that in quantities the prieces are very much lower . Embedded architecures can be very pricy and cannot compete with a high volume product .
There could be another solution and is to use a spartan3 .these are supposed to be around $35 . then the cost of a memory and the board and assemply may be can be done in 100 pieces for just under $80 .
