Publication number: 20200153615Abstract: A method for a node to issue a new block is used for a distributed system in which transactions and records are organized in block. The method comprises the steps of: determining a value R from a common reference string; computing a value s associated to a value of a status with a private key at a node, wherein the private key is a private signing key corresponding to the node, and the value s can only be computed by the node with the private key; computing a value r by taking the value s into a function H at the node, wherein the value r is unpredictable and unique to other nodes; and determining whether the node obtains a right to issue a new block by taking the values R and r into a function V.Type: ApplicationFiled: November 8, 2019Publication date: May 14, 2020Inventors: Tai-Yuan CHEN, Wei-Ning HUANG, Po-Chun KUO, Hao CHUNG, Tzu-Wei CHAO

Patent number: 10447466Abstract: A transceiver and a clock generation module are provided. The transceiver includes a receiver and the clock generation module. The receiver receives a receiving-input-data and a receiving-input-strobe. The receiver includes a data-receiving circuit for delaying the receiving-input-data and a strobe-receiving circuit for delaying the receiving-input-strobe. The clock generation module includes a calibration circuit, a phase-compensation module, and a multi-phase signal generator. The phase-compensation module compensates one of the data-receiving circuit and the strobe-receiving circuit according to a data-phase-compensation signal and a strobe-phase-compensation signal generated by the calibration circuit. The multi-phase signal generator generates shifted system-clock signals. A phase difference between the first and the second shifted system-clock signals is equivalent to a phase difference between the receiving-path-data and the receiving-path-strobe.Type: GrantFiled: December 21, 2018Date of Patent: October 15, 2019Assignee: MEDIATEK INC.Inventors: Ying-Yu Hsu, Chih-Lun Chuang, Po-Chun Kuo

Patent number: 8624434Abstract: A protection circuit, applied to a flash memory including a power supply pin, includes a capacitor and a switch. A power supply provides a reference voltage. The capacitor is electrically connected to the power supply pin and a ground point. The switch is electrically connected between the power supply pin and the power supply. When the reference voltage is higher than a threshold voltage, the switch is turned on, such that the reference voltage is inputted into the power pin via the switch. When the reference voltage is lower than the threshold voltage, the switch is turned off.Type: GrantFiled: April 6, 2010Date of Patent: January 7, 2014Assignee: MStar Semiconductor, Inc.Inventors: Meng-Shu Lee, Ching-Hsien Lee, Hao-Jung Li, Po-Chun Kuo
