What I meant by different implementation of state machine, is the way to access the JTAG core of IC or in other words the command set of JTAG.

So by standard protocal you meant that if I JTAG connecter and voltage level are common then JTAG device can be exchanged...
Re: Can we have common JTAG programmer for different devices
Thanks for you reply.
What I have understood is that JTAG connector can be of different types but they all have common singals. So if a designed could use same JTAG connector then this problem is solved.
But another problem is that...
After reading too many articles on JTAG and understanding what JTAG really does, now I have a question. Please help me in resolving this:
1. Can we have commom JTAG programmer for uC, uP, FPGA, DSP. All this device may be from same manufacturer or different.
