SL2.1.: Integrated Systems for Multimedia

T1. SoC designs for multimedia
IP (Intellectual Property) modules design and integrated systems for multimedia applications, especially on video compression following standards H.264 and SVC (Scalable Video Coding). In this activity is particularly relevant the use of hardware reconfigurability (both, dynamic and static) for the development of high performance multimedia systems. Hardware reconfigurability is used in order to improve the flexibility in the multimedia systems maintaining real time execution or to easily being adapted to different application environments.

T2. Improvement of video and images based on super-resolution techniques
This activity is based on the development of algorithms and techniques to improve video and images with super-resolution. IUMA has been working on these techniques since a decade. The activity is focused on the development of algorithms to be implemented on hardware in order to accelerate processing and increase the range of applications.

T3. Hyperspectral image processing and its implementation into integrated systems
Hyperspectral images are obtained from special sensors based on an advanced technique for obtaining information in both, the spatial and the spectral domain. This activity is focused on the design of processing systems for hyperspectral images, including hyperspectral sensors, advanced algorithms for hyperspectral image processing and the implementation of theses algorithms for real time applications. Special attention is focused on those applications in which the capture of the hyperspectral images is done in aircrafts and/or satellites.

T4. Networks on Chip
In the future micro and nano systems Chip (MNSoCs), circuit designers will encounter new challenges. The exploration of the space design of such systems requires many resources and computing time. It is necessary to evaluate many design alternatives in the architecture definition phase, and the MNSoCs wih giga order of magnitude in gates count, require intra-and inter-chip communication. Therefore, a great effort is mandatory for the development of communication architectures in scalable chips. This is the basis of this reseach on NoCs. Funtional simulation environments are developed with high flexibility and precision; advanced architectures are also implemented into NoCs as well as solutions are given to problems created by interconnections.

T5. Verification of integrated systems based on emulation
Verification of Systems-on-Chip is a time consuming task in the design process. Tools for emulation have achieved great levels of sophistication allowing a reduction in effort and time, resulting in better time-to-market. The IUMA has powerful emulation tools (such as Mentor VTS). This activity is focused on the research of emulation as means for verification of highly complex systems.

T6. Hardware/software systems for on-board satellite electronics
The modernization of on-board satellite systems involves using innovations being made for both, hardware and software. This activity emphasizes the use of new paradigms such as FPGAs, reconfigurability and others in the onboard systems. This would result in achieving lower costs, reduced production periods and lifetime extension of satellites. In the software domain there are possibilities of development based on TCL language.
