This is not needed to be in HW, because each register value is already in video controller's program memory, so the application only needs to modify those bits. The whole thing could be solved with maintaining a table of offsets for the "registers" inside the program. (it might depend on whenever the program memory can be modified per instruction or only as a whole block - at least, the second allows us to change more "registers" atomically;)
Yes, fortunately, there is no conflict. We can write the registers while the program is running. If you have more than on instruction to change, though, you'll get race conditions, and there may be problems with an instruction executed too soon after it's loaded (metastability). _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
