Abstract: Systems and methods are presented for achieving various operational modes of packetized wireless network communication, specifically IEEE 802.11 Wireless LAN (WLAN), 802.16 Wireless MAN and WiMAX communication. By providing for various operational modes an increase in the overall security of the wireless network can be realized. The invention is based on the application of a single cryptosystem and on the application of multiple cryptosystems. The invention addresses to aspects of WLAN security, namely, the protection of the information transmitted through the radio link of WLANs, and the invisibility of the network equipment, such as Access Points (APs), to unauthorized adapters.

Abstract: An interrupt controller can execute a faster interrupt service routine after an occurrence of the interrupt by writing branch instructions upon initialization of the computer environment in advance of the actual interrupt. The interrupt controller includes an interrupt mask register that receives, and stores an interrupt on/off instruction from a CPU. An interrupt priority register receives and stores an interrupt priority instruction from the CPU. An interrupt mask circuit unit selectively receives and forwards an interrupt generating signal from peripheral devices in response to an interrupt on/off instruction from the interrupt mask register. A priority determining circuit unit receives the interrupt generating signals from the interrupt mask circuit unit, determines priorities of the interrupt signals in response to the interrupt priority instruction from the interrupt priority register, and forwards an interrupt priority signal to an interrupt terminal of the CPU.

Abstract: The present invention relates to a register file in a microprocessor and operating system thereof for performing a data transfer between register cells within a register file. The register file has a plurality of register cells and an internal common bus that can directly transfer data between register cells by binding together control units for feedback transmission in each register cell to perform a direct data transfer between register cells. Each of the registers cell includes a repeater cell, a data input control unit, a data transfer control unit and a feedback transmission control unit.
