Is JTAG a hardware or software?
JTAG hardware debugging is a vital technique for diagnosing and debugging hardware and software issues in embedded systems and integrated circuits, making it a valuable tool in the field of electronics design and testing.
What is a JTAG emulator?
Typically connecting to the host PC via parallel port or USB port, the JTAG emulator provides a standard, simple way to give the development tool software a direct connection to one or more DSP devices on the target board.
Can you program with JTAG?
Here's an overview of how you can program serial memory devices using JTAG: Understanding JTAG: JTAG is a standard for testing and programming devices on a PCB. It defines a set of pins (TCK, TMS, TDI, TDO, and optional TRST) that allow for boundary scan testing and in-system programming.
Why is JTAG needed?
Processors often use JTAG to provide access to their debug/emulation functions and all FPGAs and CPLDs use JTAG to provide access to their programming functions. JTAG is not JUST a technology for processor debug/emulation. JTAG is not JUST a technology for programming FPGAs/CPLDs.
