Yes Jason, that would be the preferred method The 7500 also has an fpga. The amount of data probably dictates dma to main memory I don't know about parallel to USB products, but I assume that the won't support these kind of data rates, the microprocessor, not the USB, being the bottleneck (All of these products are mp based under the cover) 25 MHZ data collection is no trivial matter From: Jason Stahls <> To: Sent: Friday, July 29, 2011 1:20 PM Subject: Re: [ts-7000] Re: Using TS-7500 SBC to collect and transfer camera data over TCP/IP On 29/07/2011 11:56 AM, mtrav100 wrote:

Or, implement the bus interface in a dedicated micro or FPGA? Heck for that fact, use one of the TS products with a FPGA like a 7800, or 7300 and implement the bus in their FPGA, they have direct RAM access so they can buffer the data there for the application to read. -- Jason Stahls __._,_.___
