摘要： An improved system is described for allowing an embedded controller and a host processor to share access to modules in a computer system. The shared access system of the present invention enables exclusive, one-at-a-time access by a processor to a module and concurrent access by more than one processor to a module. An internal bus with two power sources is used to allow continued access by one of the processors when one of the two power sources is not providing power. Asynchronous clocking is provided to allow increased throughput to modules. An example of a protocol that allows an embedded controller to access more than one module is also described.

摘要： A memory device includes an interface controller for communication with a semiconductor device over a communication link. A clock signal is transmitted from the semiconductor device over the link to the memory device. A frequency of the clock signal may be any within a given range of frequencies. A frequency value signal conveying the value of the frequency of the clock signal is also transmitted. The interface controller includes circuitry for deriving from the clock signal and from the frequency value signal at least one timing signal for any operation in the memory device.

摘要： Disclosed is a system and method for storing a plurality of data packets in a plurality of memory buffers in a cache memory for reducing cache conflicts. The method includes determining size of each of a plurality of data packets; storing a first data packet of the plurality of data packets starting from a first address in a first memory buffer of the plurality of memory buffers; determining an offset based on the size of the first data packet; and storing a second data packet in a second buffer starting from a second address based on the offset.

摘要： An apparatus and method for providing a secure universal serial bus (USB) is disclosed. The secure USB comprises a secure channel for transferring data. A secure USB domain device is coupled to a host computer or is embedded within a host computer. The secure USB domain device comprises a USB memory device, a USB processor, a USB host controller, and an internal USB bus coupled to each of the elements of the secure USB domain device. The elements of the secure USB domain device are not accessible by the host computer. The secure USB domain device blocks the transmission of confidential information, enables the transmission of non-confidential information, and enables the transmission of encrypted confidential information.
