The stability analysis of a vision-based control strategy for a quad rotorcraft UAV is addressed. In the present application, the imaging sensing system provides the required states for performing autonomous navigation missions, however, it introduces latencies and time-delays from the time of capture to the time when measurements are available. To overcome this issue, a hierarchical controller is...
This paper describes the design of a phase synchronous detection system as a solution of the digital stage for high frequency bioimpedance computing in a four-electrodes-measuring configuration. The proposed design is implemented on reconfigurable hardware. The phase detection system is proposed as part of a bioimpedance measuring system, where biompedance value is obtained as a complex division of...
This paper describes a reconfigurable hardware implementation for wideband fractional delay FIR filters. The proposed implementation is based on a multirate Farrow structure, reducing in this way the arithmetic complexity compared to the modified Farrow structure, and allowing on line fractional delay value update. A minimax frequency optimization technique is used for computing the structure coefficients...
Nowadays, there is a clear trend in industry towards employing the growing amount of transistors on chip in replicating execution cores (CMP), where each core is simultaneous multithreading (SMT). State-of-the-art high-performance processors like the IBM POWER5 and POWER6 corroborate this CMP+SMT trend. Within each SMT core any of the well-known SMT mechanisms may be applied to face SMT related challenges...
