Colour inkjet press adopts speedy PCIe interface
Agfa Graphics has integrated PLDA's PCIe XpressRich IP core in the :Dotrix Modular, billed as the most productive industrial full colour inkjet press available today.
The PLDA EZ DMA IP is RTL-level IP that connects to either a Virtex-5 LXT or DSP-optimised SXT FPGA to provide an easy-to-use yet powerful DMA based interface to the PCIe bus.
The PLDA EZ DMA IP includes a full featured PCIe testbench and a software development kit including a PCIe software driver.
In addition to their on-chip RocketIO multigigabit serial transceivers, Virtex-5 LXT and SXT FPGAs each contain one PCIe endpoint block which implements transaction layer, datalink layer, and physical layer functions to provide complete PCIe endpoint functionality with minimal FPGA logic consumption.
This allows designers to reduce cost by integrating multiple functions into a single PCIe-enabled FPGA, preserve software investment and extend infrastructure life with scaleable bandwidth, and retarget designs without changing their PCIe interface implementation.
"Great River Technology needed an interface capable of sustained throughput of 400Mbyte/s plus for 3 and 4Gbit/s ARINC 818 applications, and our Matrix PCIe4 design has surpassed this", says Tim Keller, Director of Marketing at Great River.
"We required a very short design cycle and by utilising PLDA's EZ DMA IP core, we were able to have a working prototype quickly, significantly lowering our time to market".
"In order to acquire and process video at high speed, Great River Technology needed a high-bandwidth bus".
"PCI Express was the best technical fit", says Stephane Hauradou, PLDA's CTO.
"PLDA's EZ DMA IP used together with Xilinx Virtex 5LXT and SXT helped reduce the risk inherent with designing with PCIe".
"Using EZ DMA IP also dramatically cut design time since it provides a simple way to hook-up your design to the PCIe bus".
