A low power and dynamic reconfigurable hardware architecture of E0 algorithm is presented, which can satisfy sixteen different LFSRs in the Bluetooth telecommunication systems. The new LFSR design techniques can be also useful in any reconfigurable LFSR. To reduce the conventional switching activity, we proposed the clock-gatiing technique to implement the LFSR. As to the different low power method,...
A high-speed and dynamic reconfigurable hardware architecture of A5 algorithm is presented, which can satisfy the different characteristic of A5/1 and A5/2 algorithm. To save the hardware cost and get shorter critical path, we proposed reconfigurable clock controlling unit and output function, which can be reconfigured to realize the critical function of two algorithms. As to the different high-speed...
A high-speed and dynamic reconfigurable hardware architecture of grain algorithm is presented, which can satisfy the different characteristic of Grain-80 and Grain-128 algorithm. To save the hardware cost and get shorter critical path, we proposed tree network to implement linear and nonlinear feedback function. As to the different high-speed method, this paper perform detailed comparison and analysis...
