The charge pump comprises a plurality of transistors of which sources and drains are coupled, a plurality of overlapped transistors and a plurality of diode connection type transistors, wherein the transistors of which the sources and the drains are coupled serve as charging capacitors; the overlapped transistors are connected between the input end and the output end in a symmetric arrangement mode; and the diode connection type transistors are used for preventing the transistors of which the sources and the drains are coupled from being broken down in a charge transfer process and improving a charge transfer speed. The charge pump can be integrated on a chip by replacing the charging capacitors with the transistors of which the sources and the drains are coupled; and the problem of breakdown of the transistors can be solved by arranging the diode connection type transistors in the charge pump.

The invention provides an image brushing method and an image brushing system. The image brushing method comprises that: an image input device linearly and continuously inputs image data by using a frame as a unit; an image cache caches the image data; an image brushing controller sends the image data to an FIFO according to a reading request; and an image display reads the image data from the FIFO according to a predetermined time sequence. The image brushing method also comprises the following steps of: detecting the FIFO; and if the FIFO is empty, generating a corresponding amount of supplementary data according to the predetermined time sequence, and sending the supplementary data to the image display. The method can solve the problem of screen crash caused by insufficient bandwidth of the image brushing system of a fixed time sequence.

The invention is applicable to the technical field of a STB (Set Top Box) and provides a STB starting method and a STB starting device. The method comprises the following steps of: when the STB is started, a bootstrapper and block state information in an NAND Flash bootstrapper preserved storage region are read; the STB operates a bootstrapper initialization memory; when data in a NAND Flash is loaded into the STB, the STB loads a binary file of an initiator in a normal block into the memory until completing loading the complete initiator; and the STB operates the initiator in the memory to be started. According to the invention, the initiator is written into the normal block by acquiring the block state information in the process of burning the NAND Flash and storing the block state information into the NAND Flash; and when the STB is started, the block state information is read, the initiator in the normal block is loaded into the memory and the initiator is executed to start the STB, so that the problem of crash in the starting process, which is caused by the case that data of a bad block is possibly loaded when the bootstrapper loads initiators of more than one block, is solved.

The invention provides a data error correction method for image processing systems and a device thereof, and the method comprises a row judgment step and a column judgment step. The row judgment step: whether the receiving data size of the current row is larger than the threshold of the row width is judged, if so, redundant data is dropped, otherwise the data of the next row is adopted to make upthe current row; the column judgment step: whether the receiving data size of the current frame is larger than the threshold of the frame height is judged, if so, redundant data is dropped, otherwisethe data of the next column is adopted to make up the current frame. The method has an advantage that dead halt or other abnormal conditions of the system caused by row data deficiency or frame data deficiency can be prevented.

The embodiments of this application belong to the technical field of management and are applied to the field of smart government affairs, and relate to a method for data transmission between a WEB page and an FTP server and related equipment, including: deploying a WEB server in nodeJS, and controlling the WEB page according to the user's selection Send an ajax request to the WEB server; receive and convert the ajax request through the WEB server, and generate a pending request containing the execution operation; obtain and find out whether the user's FTP permission includes the execution operation; if so, detect whether the FTP or SFTP channel has been created; If it is not created, establish an FTP or SFTP channel between the WEB server and the FTP server with root authority, control the WEB server to send the request to be sent to the FTP server; control the WEB server to receive the return data sent by the FTP server, and transmit the return data Go to the FTP file preview interface. The user's FTP permission information can be stored in the blockchain node. The present application avoids the situation that the FTP server is down due to the excessive number of channels connected to the FTP server.

The present invention discloses a mobile terminal dual-battery control device and method. The dual-battery control device is connected with a main battery and a secondary cell and comprises a main battery detection module, a secondary battery detection module, an enabled module and a control switching module.
