PERFECT FIT

The M16C/62P microcontroller turned out to be a perfect fit for video production. The 24-MHz clock frequency makes it fast enough to generate video at a reasonable resolution. The 31 KB of embedded memory provides enough storage to hold the video picture. And, thanks to the embedded DMA controller, which handles the most intensive part of the video production, there’s plenty of processing power left to run all kinds of useful applications. I interfaced it to a CD-ROM player, but the availability of video output is an enabler for many more interesting applications.
