Architecture Synthesis of Heterogeneous MPSoCs for Highly-Demanding Applications

The spectacular progress in modern nano-dimension semiconductor technology enabled implementation of a very complex multi-processor system on a single chip (MPSoC) and facilitated a rapid progress in mobile and autonomous computing, global networking and wire-less communication. Numerous new sorts of embedded and cyber-physical systems became technologically feasible and economically justified. Various monitoring, control, communication or multi-media systems that can be put on or embedded in (mobile, poorly accessible or distant) objects, installations, machines or devices, or even implanted in human or animal body can serve as examples. However, many of the modern cyber-physical applications are very complex, heterogeneous, and impose very stringent functional and parametric demands. The combination of the huge complexity with the stringent application requirements results in numerous serious design and development challenges, such as: accounting in design for more aspects and related complex multi-objective MPSoC optimization, adequate resolution of numerous complex design tradeoffs, reduction of the design productivity gap, reduction of the time-to market and development costs without compromising the system quality, etc. These challenges cannot be well addressed without an adequate system and design methodology adaptation. The presentation discusses the serious issues and challenges in the development of contemporary and future demanding embedded systems. Subsequently, it introduces the Intel's ASIP-based MPSoC technology and discusses a new automatic design flow for heterogeneous ASIP-based MPSoCs, when focusing on the system and procesor level design-space exploration (DSE). This flow and its EDA tools are results from the European research project ASAM (Automatic Architecture Synthesis and Application Mapping for MPSoCs based on adaptable ASIPs) performed in the framework of the European industrial research program ARTEMIS. The final presentation part overviews several methods and EDA-tools of the ASAM flow focusing on the micro-architecture level DSE involving the application analysis and parallelization, ASIP micro-architecture synthesis and application scheduling and mapping, combined in one coherent HW/SW co-synthesis process.

Wither High-Level Synthesis?

High-level synthesis describes a collection of technologies for deriving implementations from abstract descriptions of a system. As a field, its success record has been mixed, in spite of undeniable progress on many fronts. Rather than focusing on the technical issues that remain to be solved, this talk will try to look at some of the opportunities for our field, and speculate about possible directions it might take. How can high-level synthesis be more relevant, and to whom, and for what? And how does it relate to other developments in adjoining fields, especially software development for highly parallel computing machines?

FPGA+HLS: New computing Paradigm for Complex Algorithm Synthesis

This paper discusses how FPGA with High Level Synthesis can change computation mechanism for control flow intensive algorithm, which has many conditional branches, conditional jump (goto). Control dependencies have been obstacles for high performance computing, or automatic parallelization, for CPU, GPGPU and also for RTL-based design hardware. However, our HLS, called CyberWorkBench, can parallelize CDFG based only on data dependencies and control dependencies are not obstacles for parallelization in scheduling. Therefore, when C program is compiled into FPGA with HLS, its performance is much better than CPU and GPGPU and even RTL-based design hardware. In this case, FPGA+HLS could be thought as a special processor customized for a single C program. This paper discusses the difference among processor, RTL-based hardware and FPGA+HLS using FMSD model, and illustrate how control dependencies are neglected for parallelization. This paper also shows some examples FPGA+HLS is used, su ch as high frequency trading(HFT), CODEC, motor control.

HLS Current State, Adoption Drivers, and Future Directions

Industry adoption of high-level synthesis has been steadily growing in the last few years especially for designs in communication and image and video processing.

The increasing design complexity is adding momentum to the wider adoption of HLS as a way to reduce the ever increasing cost of verification. This includes verification of the high-level models written in C++ or SystemC, verifying that the RTL generated by HLS is correct compared to the high-level models as well as integrating into and evolving within existing SoC verification methodologies.

HLS has also shown advantages for lowering power of designs at the high level by enabling quick exploration of the effects of architectural decisions, performing power specific optimizations at higher levels than RTL, and by facilitating the job of downstream RTL power optimizations tools.

This talk will cover the state of HLS, the drivers for adoption and the emerging requirements in terms of standards, verification, power optimization, and integration with existing RTL flows and methodologies.

Invited Talk 3: Andy Pimentel, University of Amsterdam, The Netherlands

Perspectives on System-level MPSoC Design Space Exploration

The complexity of modern embedded systems, which are increasingly based on heterogeneous multiprocessor system-on-chip (MPSoC) architectures, has led to the emergence of the field of system-level design and synthesis. To cope with the design complexity, system-level design and synthesis methods aim at raising the abstraction level of the design process. Key enablers to this end are, for example, the use of architectural platforms to facilitate re-use of IP components and the notion of high-level system modelling and simulation. The latter allows for capturing the behavior of platform components and their interactions at a high level of abstraction. As such, these high-level models minimize the modeling effort and are optimized for execution speed, and can therefore be applied during the very early design stages to perform design space exploration.  Such early design space exploration is of paramount importance as early design choices heavily influence the success or failure of the final product. In this talk, I will provide an overview of the recent advances in our research on system-level MPSoC design space exploration and will present some future challenges that need to be addressed in this domain.
