A comparative study for transforming a slow motion system (SMS) into Fast Motion system (FMS) is presented. Priority inversion problem occurs when multiple tasks are running in parallel and request the access of the resource at the same time thereby making the system response slow. In this study an existing SMS running on LPC 1768 board is transformed to FMS using real time concepts -Mutex in μcos that provides inbuilt solution for priority inversion problem by changing the priority of lowest priority task to highest priority momentarily. In the results section, SMs and FMS results are measured which are dependent on different tasks based on priority levels.Keywords

Computers have a plethora of different applications, spread over a wide spectrum of different branches such as electronic fund transfers, air traffic control, and storage of information in medical systems and so on. In all these security is an important aspect of any operating system and access of information to only properly authorized individuals or processes through the use of special security features should be ensured. The main objective of the proposed self healing scheme is to share and secure the information of any system at the same time. However, sharing and protection are two contradictory goals. Protection programs may be completely isolated from each other by executing them on separate non-networked computer, however, this precludes sharing. The proposed work provides data security based on Dynamic Information Flow Tracking by keeping track of the modified capabilities of the resources. A novel feature of this work is that the proposed architecture allows passive threats to co-exist, thus, making the architecture more user-friendly.Keywords

To reduce energy consumption, adiabatic logic families are used, which utilizes AC voltage supplies to recycle energy of circuits instead of being dissipated as heat, a flip flop is realised using PAL-2N (pass transistor adiabatic logic) logic. Using this sequential circuit is implemented. The energy saving is further attained by including power gating in the circuit. With the help of simulation results, it’s shown that energy loss for this adiabatic sequential circuit with power-gating technique is reduced greatly.- Implementation of FPAA Controller with Programmable Control Law Generator
