Hi Jaime,

Yes, a lot of processing power, besides you never have enough!

The ADSP-21161N runs at 100MHz, has 1Mbit of on chip SRAM and costs
$26. As we need the processing power of one or more Tigers, a cluster
of ADSP-21161s would be very expensive.
The ADSP-21363 runs at 333MHz, has 3 Mbits of internal RAM and costs
$17. But lacks the host port.
I hate TI's assembly language!

What will I do? :)

As I said, we sell boards, so it's not practical to bundle an external
debugger.

Our boards certainly have support for an external emulator and we also 
provide EZ-Kit Style debuggers (under license from ADI) on some of our 
boards. In both cases, we treat the JTAG port as a black box so we don't 
know any more than you about the specifics.

We also provide the capablility to upload code into flash on our boards 
using USB or RS-232 using a proprietary loader that we wrote. This doesn't 
provide debug support but it does work well for production programming and 
upgrades.

We have customers using our dspblok 21261sm with its FPGA for a host port 
interface. Depending on you application, SPI, SPORTs, USB or RS-232 are 
also possibilities with our dspstak boards.

To Luiz:

I think that if you were heading for the TS, but are also considering the 
ADSP-2136x, it's because you need some big computational power for your 
application. Couldn't a ADSP-21161 work for you? It has a host port, 
allowing you to debug it without the need of diving deep into the JTAG 
internals.

I think that Ron's suggestion of the emulator + remote access software 
(NetMeeting, VNC) could be a good option for you.

Ask Dr. Mike Rosing, maybe he could give you good advice, since his company 
(BeastRider, http://www.beastrider.com/) makes low cost JTAG debuggers for 
SHARC, 2106x and 2116x, though. Anyway, they are experienced with what you 
need.

To Ron Huizen, Jim Thomas:

Thanks for coming in, and commenting from your experience.

Regards,

Hi Ron,

We sell boards based on ADSP-218x. But it is running out of gas! We are
looking for a floating point DSP replacement. Well, even BlackFin
doesn't have a host port!
I'll try again to get more information from ADI.

Thanks,

Luiz Carlos.

Hi Jim,

My problem is the SHARC, not the TigerSHARC.
The TS permits debug using it's external bus.
Anyway it looks like you have nice tools.

Thanks,

Luiz Carlos

I don't speak for BittWare, I just happen to work here.  But...

I have not done a lot of work with the Tiger family yet, and most of 
what I have done has been mundane tasks in C, not requiring a lot of 
in-depth knowledge of the chip's architecture.

I cannot comment on the Tiger's lack of a host port - out of ignorance. 
   I do know that the host /does/ have access to the TigerSHARCs in our 
systems.

BittWare does have a host-based debugger for the TS101 and TS201.  I 
architected this debugger for the Hammerhead family, but a co-worker 
implemented it, and then ported it to the TS.

Our debugger plugs into VisualDSP++ and looks exactly like an emulator. 
  It's all software based, not requiring an emulator pod.  It even 
supports Tigers plugged into PC's other than the one on which 
VisualDSP++ is running (remote target).  I have used it, and it works 
well.  It /is/ therefore possible to debug TigerSHARC code without 
connecting to the JTAG.

I have also used it in some complex tool chains.  For instance, I run 
VisualDSP++ on a WinXP installed on a virtual machine using VMWare.  I 
do this on my laptop which runs Linux.

The laptop obviously precludes the addition of PCI boards.  I have used 
our Remote Target package to connect this virtual XP setup to other PCs 
running Windows or Linux.

So I can open VisualDSP++ on my laptop and have it open a debug session 
on a TS201 (cluster) installed in a box on the other side of the 
network.  There is no reason it wouldn't work across the Internet too 
(although I would expect it to be a tad sluggish).

Which I think is all pretty cool.

To my knowledge, this package is offered only with BittWare hardware.

We (BittWare) use the ADI emulators for JTAG debug, so have no need to try 
to figure out and run the JTAG directly.  We also have our own "secret" 
method for doing VDSP debug sessions over the PCI bus to our boards. 
However, all of our processors (2106x, 2116x, TS101, TS201) have host ports 
we can use for this.

You should contact Analog Devices and see if you can sign whatever licenses 
and NDAs they may require to get access to this information.  It may be much 
easier, however, to look at something like their USB emulators, and plug 
this into your board and the PC its in (you did say it had a PCI interface) 
assuming you're running Windows) and then just use some remote Windows 
access software (like NetMeeting).

We support remote VDSP debug sessions over TCP/IP, but it requires one of 
our PCI based boards to be in a target system (Windows, Linux, VxWorks) 
running our remote server to provide access to the DSPs.

Is this "top secret" information?

Luiz Carlos

JaaC,

Unfortunately the newers SHARCs don't have a host port. I think this
was a big mistake, and this is my problem.
I was heading a TigerSHARC (TS203), but since it's price changed form
$35 to $47, I'm looking for alternatives.
If I can't debug the SHARC by myself, I can't use it. And the only way
I could find is using the JTAG port.
I don't understand why ADI doesn't publish this information. I don't
think they do a lot of money selling debug pods.

Thanks,

Luiz Carlos
