召唤DSC介绍~

说是这一次可以用了，我想了解一下，这个DSC一般有什么型号，各个型号之间有什么区别。编程和使用上和MCU有什么区别。。  先谢谢各位高手解答，奸商也可以借此机会介绍一下，自己的DSC产品啊~

顶一个！

事先声明我不是奸商

dsc是digital signal controller
microchip公司提出dsc的概念，是想定义具有dsp功能，但又具备大量外设、主要用于工业控制的mcu。后来 就把mcu和dsp的结合体 定义为dsc。

典型芯片如ti的f28xx，microchip的dspic3xf

我也想知道

另外 友情提醒 要好好利用google和baidu

下面是wiki的定义

A digital signal controller (DSC) can be thought of as a hybrid of microcontrollers and digital signal processors (DSPs). 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. Not all vendors have adopted the term DSC.[clarification needed] 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.)

DSCs are used in a wide range of applications, but the majority go into motor control, power conversion, and sensor processing applications. Currently DSCs are being marketed as green technologies for their potential to reduce power consumption in electric motors and power supplies.

In order of market share, the top three DSC vendors are Texas Instruments, Freescale, and Microchip Technology, according to market research firm Forward Concepts (2007). These three companies dominate the DSC market, with other vendors such as Infineon and Renesas taking a smaller slice of the pie.
