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.

> 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.

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.

Vikas.

Thank u for that answer. Can't the external bus (@125MHz,16-bit)

PCI9030 is a PCI target but it acts as
a master of the localbus
interface.
If you connect BF533 to the local
bus interface, thenBF533 should act as a
slave for data transfer.
Except SPI, PPI, noother peripherals on BF533 can
be used to interface
to PCI9030. If youuse SPI, then you may have to use
some GPIOs rather
than local businterface on PCI9030. But you may not get
enough
bandwidth for the datato be transferred on PCI. If you use PPI,
then
the interface as well assoftware programming gets
complicated.
To connect any processor toPCI9030, the processor should
have an HPI(host
port interface) similarto the one on TMS320C6000(see
applicationnote
:http://www1.plxtech.com/TEMP/88884/9030-to-C6000_AppNo
te_v1.1.pdf).
Otherwise bandwidth can't be achieved with any other
interface.
Ican't see in ANALOG.COM that BF535 has been discontinued.
They
havejust
said "No more information is available regarding
productnumber:
ADSP-BF535P". But I hope they will be continuing to
produceit.
