My First Day. Sacred Heart Hospital was a private teaching hospital in San DiFrangeles, California. It offered emergency services, clinical help, and other medical processes. It had a large staff of surgical and medical doctors, and offered a great educational setting for medical students and interns.
The Joint Test Action Group (JTAG) is an electronics industry association formed in 1985 for developing a method of verifying designs and testing printed circuit boards after manufacture.
JTAG can take control (or hijack) the pins of all the ICs. On the picture, maybe JTAG is going to make all the CPU pins outputs, and all the FPGA pins inputs. Then by sending some data from the CPU pins, and reading the values from the FPGA pins, JTAG can make sure that the board connections are fine.
