Power: a significant challenge in EDA design

... to show improvement in power consumption. For example, the Samsung 28-nm low-power process delivers 35% less active and standby power at the same frequency than the company’s 45-nm low-power process, and the 28-nm process offers a 60%-of-active-power reduction at the same frequency compared with 45-nm low-power system-on-chip designs. Taiwan Semiconductor Manufacturing Co’s 28-nm high-performance, low...

Handling time delays

... of a feedback-control system?Time delays arise in control systems from delays in the process itself, represented by a time constant, τ, and a natural frequency, ωN, in transfer functions; from delays in the processing of sensed signals; and from delays in the implementation of a digital-control system as a result of sample-and-hold, calculation, and velocity estimation, in which the total time delay can be one to two times the sample period.The input-output time delay shifts the signal in time (Figure 1). The frequency response of a time delay is exact, with a magnitude of one and a phase angle that decreases...

Sensor architecture allows real-time auto emissions monitoring, Part 1

... the real-time information.Converting analog data to digital formatTo enable the sensors' data to be processed by the MCUs, one needs to convert this data into digital format. ADCs (analog-to-digital converters) can be used to convert the sensors' output into digital format, making it easier for the processing unit to store and process it.Given the type of application, one would not require constant...
