For a pattern tester the ARM's even overkill (although for bang per buck
it's hard to beat). Atmel's XMega A4's work fine for vector based stuff
with their internal DACs. A few bucks each in small quantities for the 32K
flash part. I made a vector generator for an RGB laser with three chips--
XMega32A4 and a couple TL082's-- and a little CUI 5V-> +/-15V DC/DC
converter for the analog rails. (I used the ADC inputs on the micro to
digitize sound and control the vector generator.)
