MSX VDP in FPGA

Hardware - MSX VDP in FPGA

 Sunday, November 02, 2003 - 16:13
 Submitted by: snout
 Topic: Hardware
 
After pin-compatible PSG and PPI replacements in FPGA, another interesting pin-compatible hardware product comes from Brazil. Hardware developer Marco Dal Poz and the LSI-USP team developed a replacement for the TMS9918a (MSX-1 VDP) made with FPGA, which adds new video modes of 512x192 and 512x384 pixels in 15-bit color. Needless to say, this FPGA will also support MSX2 (V9938) video modes in the future, including fast ADVRAM support. Right here you can find a movie in which this new VDP, including the new video modes, are demonstrated. However, to be able to play the movie correctly you'll need a recent version or DivX.

Hmm, the video stops exactly when the 15bit color stuff is about to be shown...

fixed it, it should work now.

am I the only one who can't play that file? GSpot still says the header is corrupt!
By Arjan on November 02 2003, 21:12
oh I see you've uploaded yet another version...

How much would such a FPGA VDP, PPI, PSG etc cost?

The developers are using low-cost FPGA chips which are quite cheap ($20)... however, it takes a lot more than 'just the chip' to make the thing work. However, the final result will probably not cost hundreds and hundreds of dollars

I wonder if the scrolling is V9958 compatible...
By ricbit on November 03 2003, 18:48
No, it isn't. There are four new registers controlling high-x-scroll, low-x-scroll, high-y-scroll and low-y-scroll. (two bytes are needed because the values can be greater than 256, of course). Also, in interlaced mode, there's no need to place consecutive lines in different pages like v9938.
