Preliminary design study of a regenerative life support system information management and display system
The instrumentation requirements for a regenerative life support systems were studied to provide the earliest possible indication of a malfunction that will permit degradation of the environment. Four categories of parameters were investigated: environmental parameters that directly and immediately influence the health and safety of the cabin crew; subsystems' inputs to the cabin that directly maintain the cabin environmental parameters; indications for maintenance or repair; and parameters useful as diagnostic indicators. A data averager concept is introduced which provides a moving average of parameter values that is not influenced by spurious changes, and is convenient for detecting parameter rates of change. A system is included to provide alarms at preselected parameter levels
A novel clock gating approach for the design of low-power linear feedback shift register
This paper presents an efficient solution to reduce the power consumption of the popular
linear feedback shift register by exploiting the gated clock approach. The power reduction with respect to
other gated clock schemes is obtained by an efficient implementation of the logic gates and properly
reducing the number of XOR gates in the feedback network. Transistor level simulations are performed by
using standard cells in a 28-nm FD-SOI CMOS technology and a 300-MHz clock. Simulation results show
a power reduction with respect to traditional implementations, which reaches values higher than 30%
