说明：  This paper will first review the features and benefits of price / performance-leading 56F8000 Digital Signal Controllers (DSCs), then investigate some applications now enabled by these revolutionary devices. Freescales’s DSCs and microcontrollers have a long and distinguished history in industrial and control applications. The new 56F8000 series is the latest addition to the widely adopted 56800/E portfolio of high-performance, Flash-based processors. The 56F8000 devices combine the capabilities of a microcontroller with the signal processing performance of a Digital Signal Processor (DSP).
