Dept of Information Technology
The Embedded Systems Laboratory performs research on multi-core architectures, and programming languages for highly parallel and distributed architectures. The application areas that we target include future multi-media applications, low-power architectures, and software defined radio. Our approach is based on a model-driven design methodology, where the systems behavior can be specified at different levels of abstraction, and emphasizing particular aspects that are relevant at that level. The design flow leads to implementations in the language Canals, which is a dataflow or streaming language, that allows explicit specification of communication patterns, dataflows and in particular scheduling strategies at different levels of granularity. The Canals application is then mapped onto a heterogenous multi-core architecture.

EEMBC will be used in the PROARTIS project (www.proartis-project.eu). PROARTIS hypothesis is that new advanced hardware/software features (such as caches or multicore processors) enabling truly randomized timing behaviour can be defined for use in critical real-time embedded (CRTE) systems. This paradigm shift will permit probabilistic analysis techniques to be used effectively in arguments of system verification and certification, by demonstrating that the probability of pathological execution times is negligible.

Assoc. Prof. Alper Sen
Prof. Sen plans to develop synthetic embedded multicore benchmarks from EEMBC benchmarks. Specifically, he will utilize EEMBC MultiBench that will allow them to develop synthetics for multicore architectures. Their synthetics will be much smaller than the original benchmarks but similar to them with respect to some performance characteristics. In order to obtain portability, they will use the newly developed standards from Multicore Association for communication and resource sharing (namely MCAPI and MRAPI libraries).
In our project, we are interested in evaluating the energy-efficiency and performance of a number of synchronization mechanisms adapted for embedded devices. We are focusing on providing simple hardware accelerators (and in particular transactional memory) for common software synchronization patterns found in embedded systems. We are evaluating our designs on a simulation framework we developed. To properly evaluate our designs, we are looking to run benchmarks representative of multicore applications for embedded systems. We believe the EEMBC benchmarks will provide us with useful insights into designing our embedded system.

The research we are doing based on EEMBC focuses on two topics. 1. We are doing research in a new class of reconfigurable architectures for the embedded space that promises to exhibit high energy-efficiency and performance while at the same time being able to adapt to workloads. We want to use EEMBC to evaluate this new architectural style which we have called FlexSoC. 2. We are also doing research in novel programming interfaces for multicore architectures. To this end, we are specifically interested in how well emerging transactional memory models can help applications in the embedded space to leverage on the compute power of multicores. We are using EEMBC to quantitatively provide empirical data for this.

My fundamental research interest lies in Computer Architecure. Previously, for the last decades or so, I was studying the memory architecture including caches in multiprocessor systems. The application domain for such systems are scientific computations and commercial applications. For the scientific applications, Stanford's SPLASH benchmark suites and, for the commercial applications, TPC benchmarks were used. Recently, I have become interested in embedded system architectures and printer systems in particular. Having licensed the EEMBC Office Automation benchmarks, I will be doing performance evaluations for a certain commercial printer system. The goal of the research is to find a methodology for designing best-performing and well-tuned printer systems. In addition, I have formed a team with my colleagues to study embedded systems for mobile systems. Networking and communication issues will be included.

Our main research focus is on Worst-Case Execution Time (WCET) analysis. Such analyses are used to derive an upper bound on the possible running time of computer programs. Derived timing bounds are key components for validating embedded real-time systems and to guarantee that no deadlines will be missed. The EEMBC benchmarks will be used to test and evaluate our developed WCET analysis techniques. Our project homepage can be found at: http://www.mrtc.mdh.se/projects/wcet/

The research we are doing based on EEMBC is mainly on the compiler technologies for VLIW DSP processors, especially for the family of DSP processors with distributed register files and multi-bank register files. To reduce the design complexity and power consumptions of VLIW DSP processors, distributed register files and multi-bank register architectures are used to reduce the amount of read/write ports needed. In addition, the register files shared by multiple functional units might not be accessible to a particular functional unit at all times to further reduce the amount of read and write ports by taking advantage of DSP application characteristics. The appearance of VLIWDSP processors with highly fragmented register file designs presents a great challenge for compilers to generate efficient codes for multimedia applications. Advanced compiler optimization techniques currently being developed in our group for such architectures include SIMD optimization schemes, low-power compiler optimization schemes, SWP schemes for distributed register files, and programming models for multi-core DSP environments. We are using the EEMBC benchmarks to evaluate the performance of our optimizing compiler schemes.

The development process of automotive embedded systems is highly complex and challenging. We meet the challenge of estimating the system time behavior of whole systems in early design phases. In this context we are investigating and developing different methods to predict the SW execution time. These methods are based on an adaption of a generic processor model to a real processor. Such a training process requires benchmarks that have to cover a wide range of SW characteristics of different domains. Therefore, we are using EEMBC benchmarks as they fulfill this requirement excellently.
Prof. Mladen Berekovic
Increasing the computational power of today??™s processor architectures is a challenging task. Since further raising the clock rates by purely optimizing the underlying CMOS technology becomes more and more complicated, the future lies in massive parallel architectures. We are contributing to the research in this field by the development of a flexible multi-processor platform (many-core). Our focuses are the hardware-software interface and the exploration of scalability limits. To acquire realistic performance feedback, we need a set of real-life application benchmarks. EEMBC suits our requirements perfectly.

We are studying the execution variability of automotive applications. By execution variability, we mean the dispersion of the execution times, which depends on many factors, for instance:
We are examining whether seven or so kernels can capture the essence of future parallel computation in many different arenas. We use EEMBC to see how well these kernels cover the embedded computing arena.

Our research project is currently exploring a range of massively-parallel single-chip architectures that place the on-chip network at the heart of their design. Our simple cores are far more deeply interconnected to each other than traditional designs and support a wide-range of parallel execution patterns. This approach permits an overlay, or virtual architecture, to be constructed that matches the most natural/efficient implementation strategy for a given application in order to reduce development time, boost performance and reduce power consumption.

University of Hertfordshire
School of Computer Science
We use the EEMBC in one of the most important areas of contemporary research in computer engineering: energy efficiency. We focus our work onto reducing the energy efficiency of costly branch predictors by dynamically hand-shaking profiled static predictions/branch removal together with a low energy branch predictor. We demonstrate that the majority predictor accesses and predictor updates are not necessary, thereby achieving saving significant amounts of energy. Our work also shows that the use of costly predictors in terms of both energy and silicon space is also not necessary.
