Some simple introductions: http://en.wikipedia.org/wiki/PIC_microcontroller http://en.wikipedia.org/wiki/Digital_signal_processor Some people classify dsPICs as DSCs. http://en.wikipedia.org/wiki/Digital_Signal_Controller "On the DSP side, they incorporate features found on most DSPs such as single-cycle multiply-accumulate (MAC) units, barrel shifters, and large accumulators." This following sentence is apparently wrong. "The term was first introduced by Microchip Technology in 2002 with the launch of their 6000 series DSCs and subsequently adopted by most, but not all DSC vendors". -- Xiaofan http://mcuee.blogspot.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
