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...
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...
Hardware description languages (HDLs) can describe a digital system at several layers of abstraction, typically starting at register transfer level (RTL). Due to the instant growth in the modern designs complexity, there is an urgent need to specify the system at the more abstract layer, the system layer. The paper deals with the problem of transformation of formal behavioral specification in HSSL...
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...
Lecture presentation represents the common approach in student's education process. However, majority of presenters do not adjust their presentation during the lecture in order to react correspondingly to the students' initiative. In this paper the novel presentation system — Tablet Presenter is introduced that is dedicated to multi-touch screen Tablet computers. It provides a lot of useful functions,...
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...
Thanks to the ever-growing complexity of contemporary digital systems the HDLs (Hardware Description Languages) and EDA (Electronic Design Automation) tools have became an inevitable part of the digital design process. To make the HDL model's complexity better manageable graphical representation of its structure is often required. Also to browse the models' extensive simulation results the proper...
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...
Digital systems models complexity requires often representation of their structure in graphical form. Also the simulation results of the models are often very extensive and for their effective browsing the proper representation is needed. We have proposed the methods for visualization of the digital systems models structure as well as their simulation outputs. The methods were designed to support...
The paper presents a knowledge and skills assessment solution developed to test the skills that the students have gained in SystemC modeling. Previously, the pen and paper form course exams were used that were popular neither with students nor with teachers. What is more, this form was not suitable for student's debugging skills verification, and the students had no possibility to check their solutions...
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...
