Abstract
Provided is a Direct Memory Access (DMA) controller which provides a function of searching for a specific pattern from data being transmitted during DMA transmission. The DMA controller stores at least one pattern value. The DMA controller compares data being transmitted to a pattern value while transmitting the data using a DMA method, and generates, in response to data matching the pattern value being detected, a signal indicating that the data matching the pattern value has been detected. The DMA controller stores an address of the data matching the pattern value in response to the generated signal.
