Re: [Discuss-OSRP:49] Re : Bandwidth target

Very interesting.
Hi All.
I am new to this list.
I am a RF Design Engineer with strong interest on SDR topic.
I own a USRP1 hardware.
My interests are for wideband spectrum analysis in 2G,3G,4G cellular band and applications for hobby (Hamradio).
I've experience with Altium,Xilinx tools, and RF design.
Cypress has recently released a USB3 bridge based on a ARM9 core , the bus side has a 100MHz 32 bits.
PCIe is really interesting Ti has PCie links on newer Cortex-A8 parts and TMS320C66x DSP.
The new TMS320C66x DSP will run natively linux with 1.2GHz multicore architecture, it really a number cruncher.
The TMS320C6A8168 is a 1.5GHz Cortex-A8 part with SATA,PCIe and gigabit Ethernet interface, it is the same architecture than on the gumstix used in the USRP-E100.

Exploring new devices for different interconnect options is awesome, but has anyone else considered a format or standard that allows a distributed system to be built out yet?
I know I started this list with the intent to bring budget minded designs to the GNU Radio project, However I also see a need for more scalable modular solutions.
In my past work experiences I made purchase decisions based on the following thought, "Would I want this in my home after it's replaced?"
More of a philosophical standpoint then anything else, I do not subscribe to planned obsolesce in any shape or form, It's better to up fit or adapt then discard.

I also received the Beta version of their FX3 SDK which seems bit harder to use than I expected; especially since there are not many sample codes available from Cypress yet.
I will release the schematics and the Gerber files after the design is finalized, but in the mean time, we will keep the design in house.
Best regards,

Locally it seem the older generation is set in their ways, and don't want to listen to the "kids"

I've seen your nice job around the new FX3 device.
I'm playing with my new toy a Pandaboard running Ubuntu Natty.
The highest bandwith bus is the GPMC bus (16 bits address/data multiplexed).
The same bus is used on Ettus E100 hardware but OMAP4 is dual core 1GHz
Cortex-A9 instead of single core 720MHz.
I aim to design a spartan6 daughter board for the pandaboard.
The next Ti silicon (omap5) will implement USB 3.0 and SATA.
Best Regards

Thanks, I had to put my simplified USRP1 design on the shelf due to funding problems. I used to work for TI designing the OMAP 3 and OMAP4, I have ordered the PANDA board but I am on waiting list for it (it is on high demand here in France and I can't order from the US due to export restrictions). Does Ubuntu support the dual core of the OMAP4? I am really curious to know that.
OMAP5 is far away, but sure is an interesting product, not sure if I will use it, TI products are a bit hard to use specially if you don't have access to the full Technical Reference Manual and their support database.
It is very interesting to know how it goes with your expansion board and what you are planning to have on it.
Best regards,
Farhad

I have made my engineering degree in Grenoble and Strasbourg.
Perhaps try to order it at Mouser, I've wait only 2 weeks.
I've filled in a exportation licence form to be able to received the
Pandaboard.
The two arm cores are supported under linux (Ubuntu or other linux flavour).
Under ubuntu you just have to take the ubuntu supplied image and write
it to a SD card.
