通信框架，一个类似apache mina的异步通信框架(TNF like apache mina)

在ADI公司dsp芯片sharc21489中通过DMA实现延时功能，配合sigma for sharc使用,输入有两个参数，一个是延时时间，另一个是延时需要放在片外那个地址。(In sharc21489 delay by the DMA function, with sigma for sharc use, there are two input parameters, a delay time, and the other is the delay needs to be placed chip that address)

基于DSP2812平台，CCS3.3，采用事件管理器EVA的T2计数器测定QEP电路脉冲个数，编码器AB相输入到EVA的指定引脚。正转则T2增计数，反转则T2减计数。亲测可用。注意一圈脉冲数为编码器线程的4倍。(DSP2812 based platform, CCS3.3, the event manager using EVA T2 of the counter circuit pulse number measuring QEP, Encoder AB input to the specified pin of the EVA. Forward is the T2 to increase the count, reverse the T2 down count. Pro test available. Note that the number of pulses is four times that of the encoder thread.)
