摘要:
A communication module coding a first original header signal as a first check signal by a first coding means, and outputs an output header signal by whitening the first original header signal and the first check signal with a clock code according to a second coding means. A method for the communication module includes obtaining the output header signal; generating a guessing clock code; dewhitening the output header signal into a second original header signal and a second check signal by a third decoding means with the guessing clock code; utilizing the first coding means to form a third check signal from the second original header signal; and comparing the third check signal to the second check signal. The third decoding means decodes the output header signal into the first original header signal and the first check signal while the guessing clock code is substantially the same as the clock code.

A method, system, and recording medium of testing 1394 interface card are disclosed in the present invention. A plurality of ports for the 1394 interface card to be tested are respectively connected to ports of a reference 1394 interface card through cables. One port of the 1394 interface card to be tested and one port of the reference 1394 interface card are in enabled condition and the others are in disabled condition. Only a reference 1394 interface card and two PCI slots are used, the testing process is simplified, and the probability of testing error is decreased.
摘要:
The address of a data packet to be transferred from a memory to a network interface card within a direct memory access (DMA) is checked. First of all, the address of a descriptor corresponding to the data packet is read from the memory, wherein the descriptor contains information of the address of the data packet. Then, whether the address of the descriptor complies with a certain rule is determined. If the address of the descriptor does not comply with the certain rule, an interrupt signal is asserted to a processor to perform a corresponding interrupt service in order to re-read the address of the descriptor.
摘要:
A wireless peripheral and control method for supporting legacy keyboard inputting. The wireless peripheral includes a wireless interface device (like a wireless keyboard) and a corresponding wireless receiving dongle. The dongle can be selectively connected to a wired input port (like a PS/2 port) or a universal connection port (like a USB port) of a host of the computer system, and the dongle has a firmware advanced control module for decoding signals of the wireless interface device to signals formatted for the wired input port. When the wireless peripheral is used for BIOS setting of the host, the dongle is connected to the wired input port, thus the advanced control module can be enabled to support a legacy input functionality of the computer system.

A wireless system has a host and a wireless peripheral, such as a cell phone and a corresponding wireless handset. When the system is in use, if a wireless connection between the host and the peripheral is disconnected, the wireless peripheral is capable of alerting a user by sound, light or vibration alarm. In addition, the host is capable of generating sound, light or vibration to indicate its location when it is disconnected.
