Video DMA Core Interfaces
There are many video systems developed that use an integrated MicroBlaze processor soft core to dynamically
control the parameters within the system. This is especially important when several independent image processing
cores are integrated into a single FPGA. The Video DMA core can be configured with one of two interfaces: an EDK
pCore Interface or a General Purpose Processor Interface.
EDK pCore Interface
The pCore interface creates a core that can be easily added to an EDK Project as a hardware peripheral. This section
describes the Register Set, the pCore Driver Files, and the I/O signals associated with the Video DMA pCore.
Once generated by CORE Generator software, the new VDMA pCore is located in the CORE Generator project
directory at <Component_Name>/pcores/vdma_v1_01_a. The pCore should be copied to the user’s
<EDK_Project>/pcores directory or to a user pCores repository. The VDMA pCore driver software is located in the
CORE Generator project directory at <Component_Name>/drivers/vdma_v1_01_a. The driver software should be
copied to the user’s <EDK_Project>/drivers directory or to a user pCores repository.
