Divide and Conquer Works for Dual-Core MCUs， Too
NXP半导体lpc4350是一个32位的ARM®皮质™-第一个实现M0／M4在单芯片。M4可以致力于高速数据平面的处理而M0处理较低速度的控制任务。通过适当划分应用软件，设计者可以利用芯片的异构多核体系结构来创建能够同时高效地处理多个任务的应用程序。目标应用包括电机控制，工业自动化，白色家电，嵌入式音频，RFID阅读器和电源管理。
本文的lpc4350功能包括评估套件的lpc4300亲自审查，演示了如何编码、下载、调试程序。这也凸显了部分的独特状态可配置定时器（SCT）和串行GPIO（sgpio）接口。。
Working ARM in ARM
The dual-core LPC4350 joins two code- and tool-compatible ARM processors that share the same buses and can work closely together. The 32-bit ARM Cortex-M4 incorporates a three-stage pipeline with separate local instruction and data buses， as well as a third bus for peripherals. It also includes an internal prefetch unit that supports speculative branching. The M4 core supports single-cycle DSP and SIMD instructions and includes an integrated hardware floating-point processor. In any given application， the M4 core does the high-speed heavy lifting.
The low-power Cortex-M0 core on the other hand， typically handles non-time-critical supervisory chores; it is designed as a low-cost 32-bit replacement for existing 8/16-bit microcontrollers. Like its big brother the M4， the M0 processor offers up to 204 MHz performance but with a simple instruction set and reduced code size.
