A Scanning Direct Memory Access controller reduced using the proposed Scanning DMA is proposed which can react in a data dependant Controller which has a mechanism to detect the manner to save software overhead of searching block delimiter, close the current buffer and start through data buffers for data structure and control tilling a new buffer. A processor interrupt can occur characters. The key to the Scanning DMA when the block delimiter is detected. Software now Controller is to scan the data as it is being moved handles data on a block basis where all data in each by the DMA controller. block relates to the same message or task.
