We present a co-simulation environment for multiprocessor architectures, that is based on SystemC and allows a transparent integration of instruction set simulators (ISSs) within the SystemC simulation framework. The integration is based on the well-known concept of bus wrapper, that realizes the interface between the ISS and the simulator. The proposed solution uses an ISS-wrapper interface ba...

The concept of interactivity and its implications for Web-based learning system design is re-examined. The author reviews the literature on the interactivity concept from the perspectives of communication, computer-assisted instruction, distance education, and interactive dimensions and functions for Web systems. A proposal is then made for a technical framework for including such dimensions an...

BACKGROUND In the problem-based learning (PBL) medical curriculum at the Arabian Gulf University in Bahrain, students construct concept maps related to each case they study in PBL tutorials. AIM To evaluate the interrater reliability and predictive validity of concept map scores using a structured assessment tool. METHODS We examined concept maps of the same cohort of students at the beginn...

New techniques for superscalar instruction issuing are presented. It is shown that the data dependency check for both in-order and out-of-order issuing can be performed in O(logw) gate delay using O(w2) primitive gates, where w is the size of the instruction buffer. Furthermore, we present a new counting based technique for assigning instructions to resources. It requires a delay of O(logw+logm...

Physiology is a core requirement in the undergraduate biomedical engineering curriculum. In one or two introductory physiology courses, engineering students must learn physiology sufficiently to support learning in their subsequent engineering courses and careers. As preparation for future learning, physiology instruction centered on concepts may help engineering students to further develop the...

Today, virtualization is often discussed on rather high abstraction levels (infrastructure, platform, software as a service). In contrast, in this talk the AMI-DAR processor concept [GH05] will be presented, which allows virtualization on the instruction set level as well as on the microarchitectural level. Running different instruction sets on the same hardware and microarchitecture is not a n...

Malware authors have recently begun using emulation technology to obfuscate their code. They convert native malware binaries into bytecode programs written in a randomly generated instruction set and paired with a native binary emulator that interprets the bytecode. No existing malware analysis can reliably reverse this obfuscation technique. In this paper, we present the first work in automati...

Machine Learning (ML) is traditionally formalized as the study of learning concepts from labeled examples. We are interested in providing a way for a human teacher to interact with a learner using natural instructions, thus allowing the teacher to communicate the relevant domain expertise to the learner without necessarily knowing anything about the internal representations used for learning. W...
