Title:
PROTOCOL-MEASURING SYSTEM
Document Type and Number:
Japanese Patent JP3492635
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a protocol-measuring system for clearly indicating both causal relations at same time, without influencing cross protocol processing in communication between two systems.
SOLUTION: A data branch part 1 inputs no.1 measuring object device input signal 30, and outputs no.1 input signal 32 and no.2 measuring object device output signal 31. A data branch part 2 inputs no.2 measuring object device input signal 40 and outputs no.2 input signal 42 and no.1 measuring object device output signal 41. A physical layer terminated part 3 outputs terminated data 33, after terminating a physical layer of the no.1 input signal 32. A physical layer terminated part 4 outputs terminated data 43 after terminating a physical layer of the no.2 input signal 42. Memory write part 5 outputs the terminated data 33 by memory write trigger signal 50 as memory write data 34.
