BlackFin onto PCI - ramp...@sify.com - Dec 15 7:19:00 2005

Dear All, I am working in interfacing BlackFin processor onto the PCI bus. Can I interface BF533 with a commercial PCI controller like PCI9030. Do I need to add any logic in between blackfin and PCI9030(or any other copmmercial. BF535 has an inbuilt PCI controller in it, but the the analog.com website says the chip is not in production. Can anyone help me out? Regards Ram

They made a PCI interface chip so their boards would work with PC's and I think they sell the chip as an independent device. http://www.bittware.com/products/type/dsp-pci.cfm Looks like it is just for sharc, but worth asking about. Patience, persistence, truth, Dr. mike

RE: BlackFin onto PCI - Vikas Chandra Rao - Dec 16 3:21:00 2005

Hi Ram, PCI9030 is a PCI target but it acts as a master of the local bus interface. If you connect BF533 to the local bus interface, then BF533 should act as a slave for data transfer. Except SPI, PPI, no other peripherals on BF533 can be used to interface to PCI9030. If you use SPI, then you may have to use some GPIOs rather than local bus interface on PCI9030. But you may not get enough bandwidth for the data to be transferred on PCI. If you use PPI, then the interface as well as software programming gets complicated. To connect any processor to PCI9030, the processor should have an HPI(host port interface) similar to the one on TMS320C6000(see application note :http://www1.plxtech.com/TEMP/88884/9030-to-C6000_AppNote_v1.1.pdf). Otherwise bandwidth can't be achieved with any other interface. I can't see in ANALOG.COM that BF535 has been discontinued. They have just said "No more information is available regarding product number: ADSP-BF535P". But I hope they will be continuing to produce it.

Hai Vikas,
Thank u for that answer. Can't the external bus (@125MHz,
16-bit) be used to talk with PCI
chip. If not so can a PLD be put
between these two to resolve the issues?

I saw in analog.com website,
in BF535 product page and in "price/package/availability"
table it was
given that "no more information". Hence i got
doubtful.

RE: BlackFin onto PCI - Vikas Chandra Rao - Dec 16 5:58:00 2005

Hi Ram,

The problem is that both PCI9030 and BF533 are masters of their 16-bit busses. Either of them should be a slave which is not the case. So, we can't connect those two busses together.

A PLD would not be sufficient. An FPGA with sufficient memory(depending on your application and bandwidth required on PCI) may do the work. But you need to choose an FPGA suitable to your requirements(cost, bandwidth, space, technical support from FPGA vendor, etc, etc).

Talk to an ANALOG person regarding BF535 and then proceed. I hope there should be some ANALOG representative in your locality. Where r u based? I can pass you their contact info if needed in a seperate mail.

Regards,

Vikas.

RE: BlackFin onto PCI - ramp...@sify.com - Jan 29 0:15:00 2006

Dear Vikas,
        Thank you for your replies.   
	I have more doubts
regarding connecting the local bus of a PCI controller like PCI9656
and
Blackfin asynchronous bus. Since i want a 64-bit PCI I have switched to
PCI9656(Instead of PCI9030).
My doubt is, You have said that an FPGA
would be necessary in connecting these two buses
together. Can you
please elaborate on your point that the Blackfin AMS bus can only be
a
master. What do you mean by this.
     Can you post or point to any
article on the net explaining this concept. It would be
a good help to
my work.

RE: BlackFin onto PCI - Vikas Chandra Rao - Feb 6 10:49:00 2006

Hi Ram,

I haven't gone through the datasheet of PCI9656. Hope you are using BF535 that has a PCI interface. Why are you using a separate PCI controller? Even if you want to use BF535's asynchronous bus, then see below.

I didn't go through the datasheet of PCI9656. However I assume that it has got a local bus interface for which it is acting as a master. I mean master because it can only initiate the transaction(asynchronous read or write). It can put the required address on it's ADDR bus and then read/write on it's DATA bus with suitable control signals(like WRn/RDn). Since the ADDR bus and control signals are output, it is termed as master. Similarly is the case with BF535. It can output address on it's ADDR bus but can't take address as input. Even it's control signals are output. Since both are acting as masters and none is ready to accept(input) address, then we can't connect them directly using their asynchronous interfaces. We have to use some glue logic(FPGA) in-between specific to our needs.

Hope you have understood.

Regards,

Vikas.
