Designing of Soft Core Processor System with Direct Memory Access (DMA) Mode

Abstract

A soft core processor system is constructed using embedded design techniques
and it is configured on Field Programmable Gate Arrays (FPGAs). The system is
accommodated to act with Direct Memory Access (DMA) mode using suitable Xilinx
Intellectual Property (IP) core. A dual data rate synchronous dynamic random access memory
(DDR_SDRAM) with 64 Mbyte capacity is introduced to the system and accessed by the
DMA controller. The controller is performed to transfer programmable quantity of data from
source address to destination address without intervention of the processor.
Spartan-3E slice is used and programmed using Xilinx Platform Studio (XPS)
which is provided by Xilinx integrated software environment at (ISE 10.1). The system
performance is tested by transferring data from matlab media to the DDR_SDRAM and viceversa,
