Is it possible to clone of the XDS510PP (TI DSP emulator) ?

[ja1st]

jtag controller ti dsp

SMC34c60 is the same as PPC34c60 in my opinion.
It "only" refreshes ISA signals on parallel interface.
But i have an idea to connect 8990 to USB.

Hi Ja1st,

It is a goog idea, Specrum Digital have done it.
Can you make a clone?

Hi,
I have any problems with reading this files from the page.
Files xds510pp_1.rar and xds510pp_2.rar uploaded by Harrylhq
are for me unvisible.
Please send me anybody this files.

Best Regards.

Hi ja1st,

usb would be great.
Do you have an original Spe*ctrum Digi*tal USB emulator?
A scan of the top and bottom pcb would be very interessting ..

Do the the Ti drivers work?

HI you ALL:

I looked at the schematics and i saw a workaround for this design //
It's possible to go USB .. by using a FTDI USB-> Parallel chip
Then you can use the parallel drivers provided for the XDSP510pp!
Windows will see a parallel port but is a USB device!
Second, the interface is only 8 bits so i discovered another JTAG TAP MASTER the 74LV8980A .. you can get samples from TI's web site.
mine are on their way !
Now here will be needed a CPU or GAL .. a very simple one ,It's up to you
to control the flow of data bewteen the FTDI chip and the 74LVT8980A!

The FTDI chip to use is the FT245BM

xds510 ti dsp emulator driver download

It's getting BETTER and BETTER ... There is an IP for a TAP controller on Opencores.org .. NOW is all possible to put all the EMULATOR compatible XDS510pp (which is now OBSOLETE and has bee replaced because is slow) in just one CPLD !

I have speed comparaisons among severals emulators the XDS510pp is at the BOTTOM .the XDS510pp + and USB version are 3 times better .
BUT still very SLOW compaired with high end products ..
The solution is to go full USB2 !

Re: Is it possible to clone of the XDS510PP (TI DSP emulator

Hello eltonjohn!
it is not posible to use FTDI chip as a parallel port for XDS510PP because spectrumdigital`s drivers do not use parallel port driver . the use .dll which address directly the parallel port and some giveio like driver for nt users.
speeding up the things is possible with implementing EPP mode on XDS510PP_CPLD as I sayd in the ReadMe.txt file but now I don`t have time to do this.
Implementig ACT8990 on CPLD in not possible ... you must use FPGA but it si really hard work and a lot of time.

I agree that hook up to usb 2.0 will be a good choice. DSP USB 1.0 ICE is as slow as serail port.

For small dsp code. This P port one is OK.

Hi KRAS
Good Tip .i didn't know about how the port was addressed .Maybe the driver can be patched . I've been trying to get The driver but their download site is now locked. Otherwise chances are that whole synthetized thing might fin inside a CPLD .. i took an JTAG TAP iP + the SMC34C60 VHDL code . and did synthesis on a 144 Cell CPLD and i got 75% Usage .The configuration registers and counters remaining might fit inside a 144.

hello eltonjohn!
can you tell me where I can get this JTAG TAP iP + the SMC34C60 VHDL code to take a look ?

Re: Is it possible to clone of the XDS510PP (TI DSP emulator

Yes MY LORD!

The tap is avalaible from opencores.org and the other thing is RIGHT here
in the CPLD_XDS510..

If you can't OPEN the PROTEL database ,let me know .. I ll get you the files!

I found an implementation of EPP slave on the web.

**broken link removed**

It may help for improving performance of the CPLD replacing SMC34C60.

I found another VHDL implementation of EPP on the wen.
But I am not sure it will work or not, I am a novice in VHDL.

Would anyone check this ?

Re: Is it possible to clone of the XDS510PP (TI DSP emulator

Yes I can open CPLD_XDS510PP design database .. I made this design and the VHDL source )))
I`ll search opencores.org for TAP IP..
about visioneer idea for EPP implementig I`ll say that I "lie" spectrumdigital`s driver that this device support Daisy chain protocol i.e. the protocol is not implemented .. is it some pseudo version of that... I write EPP mode many times but there is conflict between pseudo Daisy chain protocol that I implenet and EPP mode .. Implementing the full Daisy chain protocol is really hard because you need Clock signal and many many macrocells or just time to do this which I haven`t .. But I have some new ideas about this implementation and in the near furture I`ll try to make it )

I tried to download, but the link is broke. But I have two differents aproaches for XDS510, with PCB and SCH.
One use the SMC34C60, and other use Xilinx XC95108-20.
