Managing the power in highly-integrated systems on chips becomes inevitable in modern designs. Complex systems require complex power management, and it is always difficult to determine whether the designed power management is the most efficient. In our previous work, we have proposed a simplified power-management specification method at the system level of abstraction. In this paper, we propose a...
Power management becomes an integral part of hardware-systems design. In modern complex systems, the powermanagement design is not a simple task and it is quite difficult to evaluate whether the designed strategy is the best. In this paper, we propose a new method for overhead estimation of the required power-management unit, based on system-level abstract specification. It enables a designer to explore...
High power density is the most crucial problem in deeply integrated hardware systems. Therefore, the power has to be reduced in such systems, what is most commonly achieved by the utilization of power management. Unfortunately, the standardized application of power management is quite complex and does not very well support the system level of design abstraction, which is increasingly used by the industry...
Design automation is very important in modern systems-on-chip development, complexity of which is ever growing. The most crucial issue in highly integrated systems is the increased power density and the corresponding temperature problems influencing reliability. Therefore, the power must be managed in such systems. Power management enables to implement various power-reduction techniques, such as power...
Power consumption becomes a dominant problem in current hardware-systems design. It is most commonly dealt with use of power-management techniques, such as clock gating, power gating, or voltage and frequency scaling. In modern complex systems, power-management adoption is difficult to achieve, and therefore new approaches to simplify power-managed systems design are evolving. We have also proposed...
Power management is an integral part of almost every new system design. It enables to keep the power under constrains, implementing such power-reduction techniques as power gating, multi-voltage design, or voltage and frequency scaling. Due to the complexity of modern designs, the system level of abstraction is adopted as a design starting point. However, the power management is not yet fully adopted...
Power consumption is the greatest concern in current highly-integrated hardware-system design. The power reduction is targeted mostly through power management, implementing such techniques as clock gating, power gating, or voltage and frequency scaling. Due to growing complexity, the start-point in the design has moved from the register-transfer level to the system level. However, the power management...
Since the power consumption has become the key aspect in almost every digital-system design, many advanced power-reduction techniques have been developed to minimize power. The most popular strategy to apply these techniques is adoption of so-called power management. The control signals for the power-management elements are generated by power-management logic. When centralized in one system block,...
Power consumption is a very important aspect in almost every electronic system design. To minimize the power consumption, many advanced power-reduction techniques have been developed based on a power management. In modern systems the power management unit (PMU) is typically a complex circuit and therefore should also be targeted by power-efficient design techniques. This paper is focused on the design...
The increasing trend in using mobile devices causes the power consumption to become the key aspect in modern digital systems design. The current flow for low-power design involves the use of some power-reduction technique at the RTL (Register Transfer Level) or lower levels. This paper describes an extension of current low-power design flow. It proposes the power-intent specification based on UPF...
The usage of the HDLs (Hardware Description Languages) in the present digital system development process is indispensable. Although, their great contribution is undeniable, they also bring about several disadvantages. The textual form of an HDL model is less illustrative for a human being than schematic representation of its structure. Moreover, simulation of such models is most commonly displayed...
Nowadays the digital systems design is almost exclusively realized using hardware description languages (HDL). In Europe, the VHDL (Very-High-Speed Integrated Circuits HDL) is the most widely used HDL. Although HDLs brought a lot of advantages into the design process, the HDL structural models, especially on register transfer and lower layers, are harder to read than the previously used schematic...
