Divide and Conquer Works for Dual-Core MCUs， Too

　　NXP半導體lpc4350是一個32位的ARM?皮質?-第一個實現M0／M4在單芯片。M4可以致力于高速數據平面的處理而M0處理較低速度的控制任務。通過適當劃分應用軟件，設計者可以利用芯片的異構多核體系結構來創建能夠同時高效地處理多個任務的應用程序。目標應用包括電機控制，工業自動化，白色家電，嵌入式音頻，RFID閱讀器和電源管理。

　　本文的lpc4350功能包括評估套件的lpc4300親自審查，演示了如何編碼、下載、調試程序。這也凸顯了部分的獨特狀態可配置定時器（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.
