A digital signal controller (DSC) can be thought of as a hybrid of microcontrollers and DSP processors. Like microcontrollers, DSCs have fast interrupt responses, offer control-oriented peripherals like PWMs and watchdog timers, and are usually programmed using the C programming language, although can be programmed using the device's native assembly language. On the DSP side, they incorporate features found on most DSPs such as single-cycle multiply-accumulate (MAC) units, barrel shifters, and large accumulators. It should be noted that not all vendors have adopted the term DSC. 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. For example, Infineon and Renesas refer to their DSCs as microcontrollers.)

Mark Twain quote for the day:

Nobody except he has tried it, knows what it is to be an editor. It is easy to scribble local rubbish, with the facts all before you; it is easy to clip sections from other papers; it is easy to string out a correspondence from any locality; but it is an unspeakable hardship to write editorials. Subjects are the trouble - the dreary lack of them, I mean. Every day it is drag, drag, drag - think, and worry and suffer - all the world is a dull blank, and yet the editorial columns must be filled. Only give the editor a subject, and his work is done - it is no trouble to write it up; but fancy how you would feel if you had to pump your brains dry every day in the week, fifty-two weeks in the year. It makes one low spirited simply to think of it. The matter that each editor of a daily paper in America writes in the course of a year would fill from four to eight bulky volumes like this book! Fancy what a library an editor's work would make, after twenty or thirty years' service. Yet people marvel that Dickens, Scott, Bulwer, Dumas, etc., have been able to produce so many books. If these authors had wrought as voluminously as newspaper editors do, the result would be something to marvel at, indeed. How editors can continue this tremendous labor, this exhausing consumption of brain fibre (for their work is creative, and not a mere mechanical laying-up of facts, like reporting), day after day and year after year, is incomprehensible. Preachers take two months' holiday in midsummer, for they find that to produce two sermons a week is wearing, in the long run. In truth it must be so, and is so; and therefore, how an editor can take from ten to twenty texts and build upon them from ten to twenty painstaking editorials a week and keep it up all the year round, is farther beyond comprehension than ever. Ever since I survived my week as editor, I have found at least one pleasure in any newspaper that comes to my hand; it is in admirng the long columns of editorial, and wondering to myself how in the mischief he did it!
