SMASHING: The Myth of Speed and Power was a Nintendo print advertising campaign in 1994 against Sega's Blast Processing Television commercials. The advertisement was designed to look like a regular magazine article, and focused heavily on the Genesis not having any kind of special chip called the "blast processor" or a special chip that produces "blast processing." Nintendo elevated its custom processors and Dynamic Memory Access (DMA) design, above what was already found in the Sega Genesis, while pointing out other marginally advantageous, misleading, or vague to meaningless hardware specifications. SMASHING is simply a case of ill-phrased self promotion.
As the Blast processing TV commercial clearly shows, Sega only stated the Genesis "has blast processing." Sega even admitted to the press that Blast Processing was just a marketing buzz word. Endless discussion ensued about whether Blast Processing emphasized the Genesis CPU's speed over the Super Nintendo's, DMA, or some software technique for moving objects faster than the screen would scroll. Debate over each technical aspect of that argument will be covered more thoroughly in a review of the Blast Processing advertising campaign, Nothing from Sega ever claimed there was a special chip in the Genesis that was called or produced "blast processing". Interestingly, it was Nintendo that created the notion of a Blast Processor and the game media ran with it.
The average consumer would have seen the actual Blast Processing commercial (4.4 MB) by the time of seeing this fake editorial:
