Can someone explain exactly what an emulator does. I am working with the 5402 DSK and haven't availed myself of this feature out of ignorance. I can't find a good explanation of it's function. Also, is the JTAG interface just another interface specification, like RS- 232 and IEEE 1394? Any insight is, as always appreciated. Mike |

The JTAG emulator uses logic built into the DSP chip that allows you to
set breakpoints, single step and otherwise control and observe the operation of the DSP. JTAG refers to a high speed serial interface that allows all this to be done over a 14 pin connector. Yes, JTAG is an interface spec, IEEE-something, but also describes how JTAG can be used for controlling the IOs on a chip as would be used in board test. Does that help? There are lots of references on the web including the TI web site. In fact TI was one of the early promoters of JTAG and have a lot of good info.
