Abstract
A hardware monitoring interface unit (HMIU) is coupled to a data processing unit and receives all information transferred between subsystems of the data processing unit. Programmable hit matrices (PHM's) include input latches for receiving the information, memory circuits for storing binary ONE's in locations addressed by predetermined portions of the information and output latches for storing the binary ONE's or 'hit' signals read from the memory circuits. The 'hit' signals are plug-wired into logic circuits and counters in a monitor to collect statistical data.
