It has been very innovative concept in getting JTAG and functional emulation control together within PCI based controller. In fact emulation and JTAG work togather as emulation took the data i/p from JTAG to debug. Thus to have a controller which seperates JTAG specifica operations and Emulation operations will fasten the process as well have better control.
This is very much acceptable concept because of above mentioned advantages.Nice to know about this.
