Q's Fact of the Day

Blast Processing was a marketing term coined by Sega to advertise the fact that the Sega Mega Drive/Genesis could calculate faster motion than the Super Nintendo Entertainment System and was generally taken by the public to refer to the main system processors. Strictly the term refers to a technical feature of the Genesis that wasn't replicated on the SNES - the ability for the CPU to be working on one visible section of map while the graphics processor displays another. Since only the visible part of the map is uploaded at any one time, this feature greatly increases the distance that the map can scroll from one frame to the next, but few if any people will have been able to discern that meaning from the advertising.

I always wondered what that term really meant.
