DLPC410: How to meet the max pattern rate of DLP9500 in DLPC410 platform?

user5911856
Prodigy 130 points
Part Number: DLPC410
Other Parts Discussed in Thread: DLP9500, DLPLCRC410EVM,

Hello,

According to the datasheet of DLP9500,the max pattern rate is 23418Hz. But DLPLCRC410EVM can not meet the requirment.

So, how can I design to meet the requirment as much as possible? Change FPGA, change to DDR3 or some others?

Thanks!

    Hello Sunny,

    Nice to meet you.

    We had a similar question this week and here is the response from Fizix:

    "The EVM is capable of the speeds listed, but this will require the end user to program patterns that can be generated by an algorithm and displayed. This is done by writing a program (typically in VHDL or similar) to be loaded into the APPS_FPGA (Virtex V - LX50) and run. 

    If a pattern buffer is desired, there is a memory slot on board that is connected to the APPS_FPGA.  It can be populated and a memory controller set up to manage the data being sent tot he DLPC410 controller (Virtex 5 - LX30).

    There is also an EXP bus connected to the APPS-FPGA that can be set up to receive external data.  

    The APPS_FPGA is a sandbox for the user to program according to their needs.

    The GUI and its source code show how data is sent to the controller, but the USB interface does not have the bandwidth to stream data at the full speed the Controller/DMD is capable of."

    If the development kit does not meet your needs, we do have third parties that offer application specific modules. Please see this link on ti.com and scroll down through the third party offerings. https://www.ti.com/product/DLPC410?keyMatch=DLPC410

    Hope this helps you with an understanding of the kit capabilities. Please let us know if you have further questions.

    Regards,

    Matt

    Hello Sunny,

    Matt's suggestion to look at our third party offerings is a good way to get started if you do not have experience with DLP technology.  The EVM board hardware is capable of reaching the speed with VHDL or similar programming, but not through streaming over USB.

    Let us know if you need further information.
