IN-CIRCUIT EMULATOR Russian patent published in 1998 - IPC

FIELD: computer engineering, in particular, systemic debugging of hard- and software of microprocessor system and control devices which are based on MCS-48, MCS-51, UPI-42 microcontrollers. SUBSTANCE: device has design system interface unit, address registers unit, interrupt unit, unit for tracing through processor cycles, unit for read/write control, memory unit for program under debugging, data commutator, microprogram control unit, control register, state commutator, unit for generation of program interrupt instruction, microcomputer emulation unit, control board unit. Emulator of most complex microcomputer 8052 is used as emulator of MCS-48, MCS-51, UPI-42 microcomputers and their Russian analogs. Device also provides operations in capture mode. EFFECT: increased functional capabilities. 5 dwg
