Running the PCI Express
DMA Demos
This chapter describes the Lattice PCIe Direct Memory Access (DMA) demos
that you can run within this kit on a Windows system (Microsoft Windows
2000, Windows XP SP2, Windows Server 2003).
The DMA demos illustrate Lattice PCIe and Scatter-Gather DMA (SGDMA) IP
cores working together to transfering data over the PCIe bus. The SGDMA
operates as a Master DMA, reading and writing data to PC system memory.
One demo illustrates moving large amounts of image data from the solutions
board to PC system memory and display on the screen. The other demo
implements a simple hardware image processor, in which pixel data from a
source image on the screen is read by the board, modified by the hardware
and written back and redisplayed. A test program is also provided that checks
all the driver and IP functionality.
Before beginning this demo, you must do the following operations.
Use ispVM to download the bitstream for this demo to the solutions board.
You can find the x1 and x4 bitstreams and the XCF file necessary for
ispVM in the <kit_dir>\Demonstration\PCIeDMA\Bitstreams directory
path.
For general information ispDOWNLOAD cable on ispVM configuration
software usage, see the following:
