摘要： The present invention provides a high-side driver circuit including a power transistor, the first transistor, the second transistor, the second capacitor, the second diode, a start-up circuit. The start-up circuit is coupled between a resistor and the second capacitor to complete a gate driving circuit. And, the aforementioned resistor can either be the gate resistance of the power transistor or an external resistor. The design of start-up circuit enables the functionality of the bootstrap capacitor of being charged to a designate voltage level. Thus, the depletion-mode transistor can be controlled to turn on/off without a floating voltage source or a negative voltage source.

摘要： An electronic device includes a multi-field sensor, a memory, and a codec wrapper module, in which the codec wrapper module includes at least one encoder and at least one decoder. The encoder compresses raw data of an image into an image bit stream with a compression ratio through the following steps. The image is segmented into various image bands. Storage space is allocated in the memory and is segmented into various compressed band regions according to the compression ratio and a bit stream length of the raw data. A starting position of each compressed band region is recorded as a current ending position. Lines, sequentially received, are compressed into compressed bit streams respectively. The compressed bit streams are sequentially written into the corresponding compressed band regions according to field indexes of the lines, an output field order, and a group formed by the image bands corresponding to the lines.

摘要： A compressing method is applicable to compress of an image at a fixed compression ratio, in which the image has a raw data. The compression method includes the steps of receiving the raw data with a predetermined length as a compression unit; compressing the compression unit into a compressed bit stream, wherein a total length of the compressed bit stream being not larger than a target bit stream length; when the total length of the compressed bit stream is smaller than the target bit stream length, appending a dummy code to the compressed bit stream, so that a bit stream length of the compressed bit stream with the dummy code is equal to the target bit stream length; and repeating steps until the raw data is compressed into an image bit stream.

摘要： A bulk transfer control method of a universal serial bus (USB) device includes a timer for counting transmission time of a buck transfer. When the transmission time counted reaches a transmission time setting value, a trigger signal is issued to a transfer end event generator. Then, the transfer end event generator issues a transfer end event signal to a data processing unit so as to end the bulk transfer. Moreover, a USB device and its bulk transfer control circuit are also provided.

摘要： A drawing control method, a drawing control apparatus, and a drawing control system for embedded system are provided. The present invention adopts an independent drawing control apparatus to control a drawing unit to draw a frame, and move the drawn frame to an external frame buffer in advance, and therefore the number of lines that can be drawn is not restricted by the capacity of the memory of the drawing unit. Further, the present invention employs a counter to accumulate a counting number upon each time completion of drawing frame or moving frame. Whenever the counting number is accumulated, the drawing unit is controlled to perform a next stage of frame drawing or frame moving. In this concern, the present invention eliminates the time for external accessing, and thus achieving parallel processing, and instant displaying.

摘要： A card reader with capability of adjusting the access interface display is provided, including a connection interface for electrically connecting to the host, a plurality of access interfaces for electrically connecting to corresponding memory cards, such as SD, CF, and a controller. When the host completes the enumeration, the controller issues a disconnect signal through the connection interface to the host to erase the original disk mappings, such as G:, F:, on the display for subsequent adjustment. For adjusting the display, the controller issues an optional reconnect signal belonging to the card reader to the host so that the host can execute the re-enumeration and adjust the displaying of the access interface available in the card reader according to the optional reconnect signal.
