09:25 PM Feature #13: 32x speed cpu without wait states
Nope, this is not going to be so simple... Massive timing violations. foft

10:15 PM Feature #14: Svideo core for first prototype
Debugged in isim to get lots of overflow/underflow/blanking/burst incorrect cases!
Added colour bars and asserts for...

06:40 AM Feature #14: Svideo core for first prototype
Scaled luma with 64 space for chroma - when in composite mode only. No point throwing away svideo brightness.
Adde...

08:54 PM Feature #14: Svideo core for first prototype
Setting this up in the simulator so I can understand chroma better.
The problem seems to be that I've used all the...

08:51 PM Feature #13: 32x speed cpu without wait states
I have something working on the simulator - alone. Now need to plug it into the core proper to see if it works. Will ... foft

10:14 PM Feature #14: Svideo core for first prototype
Should add that this should not be done for direct chroma output for svideo... Since that is still on a 0-0.7V DAC ou... foft
10:14 PM Feature #14: Svideo core for first prototype
Panos tried out a new core with composite only - on green using the sync pin. Looks brighter but just black and white... foft
07:58 PM Feature #14 (Closed): Svideo core for first prototype
Waiting the Chinese sun to rising, I decide to proceed with the "video mod" of our v 1.0 board. So I desolder the "vs... foft

10:07 PM Feature #13 (In Progress): 32x speed cpu without wait states
Trying simply feeding in the clock at twice the speed to see if it passes timing! foft
