Abstract:
An electronic device and data transmission protection device thereof are provided. The data transmission protection device includes an input clock signal detector and a control signal generator. The input clock signal detector receives a reference clock signal, and detects a frequency of an input clock signal provided by a host end according to the reference clock signal, and frequencies of the reference clock signal and the input clock signal are different. The control signal generator enables a generated control signal when the frequency of the input clock signal is larger than a safety setting value. The control signal is used to disable the host end to perform a data accessing operation on a protected circuit.

Abstract:
An adaptive serial general-purpose input output (ASGPIO) interface and a signal receiver thereof suitable for a secure control module (SCM) are provided. The ASGPIO interface includes a signal transmitter. The signal transmitter includes a first data buffer, a comparator, and an encoder. The first data buffer receives transmitted data and provides previously transmitted data. The comparator receives currently transmitted data and receives the previously transmitted data. In a first mode, the comparator compares the previously transmitted data with the currently transmitted data to generate a data variation information. The encoder, in the first mode, generates at least one index value and a corresponding instruction signal according to the data variation information. The signal transmitter sends the at least one index value as a serial signal and the instruction signal to a signal receiver.
Abstract:
A server system is disclosed. The server system comprises a host system, at least one hard disk (HD) drive, a host bus adapter (HBA), at least one indicator, a storage enclosure processor (SEP), a baseboard management controller (BMC) and a snoop device. The HBA is used to issue a bus signal in a format suitable for transmission over a serial bus according to the received drive state from the at least one HD drive and send the bus signal over the serial bus. The SEP receives the bus signal over the serial bus and drives the at least one indicator to corresponding states. The BMC is coupled to a network. The snoop device detects the bus signal over the serial bus and sends a warning signal to the BMC when a drive failure event is detected.
Abstract:
A power measurement circuit is disclosed. The power measurement circuit comprises a sampling register, a latch generator, an accumulation unit, a calculation unit and an output register. The sampling register samples an input signal based on a sampling clock to generate a binary digit. The latch generator generates a latch signal based on the sampling clock and a measurement interval. The accumulation unit accumulates the binary digit based on the latch signal to generate a sum value. The calculation unit calculates an ON-phase rate of the input signal according to the sum value and the measurement interval. The output register stores a power consumption value according to the ON-phase rate of the input signal.

A method and apparatus for displaying images is disclosed. The method of the invention includes the steps of: transferring a content of a first one of the display buffers to the display device; overwriting a second one of the display buffers with first image data, wherein the first image data represent data of updated pixels between two corresponding adjacent frames; obtaining a bit-map mask according to the updated pixels, wherein the bit-map mask indicates altered pixels for the two corresponding adjacent frames; and, then overwriting the second one of the display buffers with second image data from the other display buffers according to at least one bit-map mask.
Abstract:
A baseboard management controller is disclosed. The baseboard management controller adapted to monitor a host comprises a baseboard management control module, a memory controller and a video graphic array (VGA) module. The VGA module comprises a video controller, a decoder, a select circuit and a mapping circuit. The decoder receives a transaction signal from a first local bus and decodes a first address signal contained in the transaction signal. The select circuit selectively transfers data from one of the microprocessor bus, the video controller and the memory controller back to the first local bus according to a control signal. The mapping circuit being connected with the decoder maps the first address signal and a second address signal to a third address signal, updates the first address signal and transfers an updated transaction signal.
