  This study proposes a method of high-speed data transfer by Advanced Microprocessor Bus Architecture (AMBA) based Direct Memory Access (DMA) controller using asynchronous first in first out (FIFO). Direct Memory Access Controller (DMAC) is designed to read/write data from/to dual ram. The DMA controller is a synthesizable Intellectual Property (IP) core for easy integration into System on Chip (SoC) implementation and it enables transferring the blocks of data from memory to peripheral and vice versa. This transfer of data appreciably reduces the load on the processor. The design is implemented in Verilog Hardware Description Language (HDL) and it may use in microprocessor based SoC for high-speed data transfer. It increases the data transfer speed as compared to original Microprocessor Unit (MPU) based architecture and provides more data transfer rate compare to conventional DMA method. With 162 Slice Look-Up Tables (LUTs) the design has achieved 306.24 Mhz maximum frequency. The proposed architecture is especially suitable for MPU based SoC for high speed large data transfer.
