DEVICE FOR VISUAL CONTROL OF PROGRAM EXECUTION Russian patent published in 1994 - IPC

FIELD: computer engineering. SUBSTANCE: device has unit 1 for registers of current address and data, mode setting unit 2, multiplexers unit 3, initial address register unit 4, comparison unit 5, memory unit 6, number selection unit 7. In addition device has group of inputs for states and synchronization, address input and data input. This inputs serves as device inputs for connection to state synchronization output, address and outputs of controlled device. In addition device has first clock pulse input of memory unit, group of inputs for control of mode in unit for registers of current address and data, group of inputs for control of mode in unit for registers of initial address, which serve as control inputs of device for connection to corresponding outputs of mode control in microcomputer. EFFECT: increased amount of information , increased precision, increased speed. 9 dwg
