Patent number: 10191883Abstract: An inter-integrated circuit bus arbitration system includes a first master circuit, a second master circuit, an analog switch circuit, an initial state identification circuit, and a selection control circuit. When the first master circuit is initiated to transmit data, the initial state identification circuit generates a first initial pulse signal. When the second master circuit is initiated to transmit data, the initial state identification circuit generates a second initial pulse signal. If the first initial pulse signal leads the second initial pulse signal, the selection control circuit generates a first control signal to make the analog switch circuit establish electrical connections between the first master circuit and an external data line and an external clock line when receiving the first control signal.Type: GrantFiled: March 22, 2017Date of Patent: January 29, 2019Assignees: Inventec (Pudong) Technology Corp., Inventec CorporationInventors: Tsung-Hsi Lee, Wei-Liang Chen
