找到一個dma的ads工程，將其dma功能整到了原來的ads工程TQ2440_Test裡面
用Linux公社（Linuxidc.com）提供的main.c替換原來TQ2440_Test的main.c

之所以要介紹DMA，因為它對性能太重要了！只有活用了DMA，CPU的性能才能上去！S3c2410有四個DMA，每個DMA支持工作方式基本相同，但支持的source Dest可能略有不同，具體見Datasheet。
這裡具體DMA CONTROL寄存器（DCON）的配置說明，進而引出DMA的各種工作方式。
Atomic transfer：指的是DMA的單次原子操作，它可以是Unit模式（傳輸1個data size），也可以是burst模式（傳輸4個data size），具體對應DCON[28]。
Data Size：指的是單次原子操作的數據位寬，8、16、32，具體對應DCON[21:20]。
Request Source：DMA請求的來源有兩種，軟件＆硬件模塊，由DCON[23]控制；當為前者時，由軟件對DMASKTRIG寄存器的位0置位觸發一次DMA 操作。當為後者時，具體來源由DCON[26:24]控制，不同硬件模塊的某時間觸發一次DMA操作，具體要見不同的硬件模塊。
DMA service mode：DMA的工作模式有兩種，單一服務模式＆整體服務模式。前一模式下，一次DMA請求完成一項原子操作，並且transfer count的值減1。後一模式下，一次DMA請求完成一批原子操作，直到transfer count等於0表示完成一次整體服務。具體對應DCON[27]。
RELOAD：在reload模式下，當transfer count的值變為零時，將自動加src、dst、TC的值加載到CURR_DST、CURR_SRC、CURR_TC，並開始一次新的DMA傳輸。該模式一般和整體服務模式一起使用，也就是說當一次整體服務開始後，src、dst、TC的值都已經被加載，因此可以更改為下一次
服務的地址，2410說明文檔中建議加入以下語句來判斷當前的服務開始，src、dst、TC的值可以被更改了：while((rDSTATn & 0xfffff) == 0) ;
Req&Ack：DMA請求和應答的協議有兩種，Demard mode 和 Handshake mode。兩者對Request和Ack的時序定義有所不同：在Demard模式下，如果
DMA完成一次請求如果Request仍然有效，那麼DMA就認為這是下一次DMA請求；在Handshake模式下，DMA完成一次請求後等待Request信號無效，然後把ACK也置無效，再等待下一次Request。這個設計外部DMA請求時可能要用到。
傳輸總長度：DMA一次整體服務傳輸的總長度為：
Data Size × Atomic transfer size × TC（字節）。
