steven niu / mDMA Featured

mDMA implements DMA APIs for mbed. It is inspired by modDMA and simpleDMA. Compared with other mbed DMA implementations, mDMA has new features like 1) support LLI 2) support more than 4KB data transfer 3) support vectorized transfer. 4) support burst transfer. 5) Improved memory-memory transfer. It could beat memcpy 6) The library implementation fit the code structure of mbed sdk. Currently only support LPC1768 but could be extended to other platforms.
