Proceedings of the 5th International Workshop on Reconfigurable Communication-centric Systems on Chip 2010 - ReCoSoC\u2710 - May 17-19, 2010 Karlsruhe, Germany. (KIT Scientific Reports ; 7551)

ReCoSoC is intended to be a periodic annual meeting to expose and discuss gathered expertise as well as state of the art research around SoC related topics through plenary invited papers and posters. The workshop aims to provide a prospective view of tomorrow\u27s challenges in the multibillion transistor era, taking into account the emerging techniques and architectures exploring the synergy between flexible on-chip communication and system reconfigurability

From Smalltalk to Silicon: Towards a methodology to turn Smalltalk code into FPGA

International audienceDue to their ability to combine high performances along with flexibility, FPGAs (Field Programmable Gate Array) are used in robotic applications nowadays, especially in case of realtime applications. The FPGA circuits are often designed and configured using the Hardware Description Languages (HDLs) like VHDL or Verilog. However, although these languages provide abstractions up to the functionality level, they lack many features of todays modern languages that make them unsuited for high-level models and systems. In this paper, we present an overview of a methodology that uses a Dynamic Reflective Language, such as Smalltalk, for high level hardware/software co-design on FPGAs

Remarkable Challenges of High-Performance Language Virtual Machines

Language Virtual Machines (VMs) are pervasive in every laptop, server, and smartphone, as is the case with Java or Javascript. They allow application portability between different platforms and better usage of resources. They are used in critical applications such as stock exchange, banking, insurance, and health [25]. Virtual machines are an important asset in companies because they allow the efficient execution of high-level programming languages. Nowadays, they even attract investments from large non-system companies, e.g., Netflix 1 , Meta 2 , Shopify 3 and Amazon 4. VMs achieve high-performance thanks to aggressive optimization techniques that observe and adapt the execution dynamically, either by doing just-in-time compilation [5] or by adapting the memory management strategies at runtime [90, 91]. For all these reasons Virtual Machines are highly-complex engineering pieces, often handcrafted by experts, that mix state-of-the-art compilation techniques with complex memory management that collaborate with the underlying operating systems and hardware. However, besides some well-known techniques that are published in research venues, most knowledge and technology around virtual machines are highly concentrated in large companies such as Microsoft, Google, and Oracle, making Virtual Machine construction difficult, and experiments difficult to reproduce and replicate. Language VMs present many multidisciplinary scientific challenges that appear at the intersection of fields such as hardware, system software, compiler, and software language engineering. This document aims to give a brief overview of the current challenges the VM community faces. To keep this document short, we selected remarkable challenges in managed execution, managed memory, performance evaluation, software engineering and security

FPGAs virtuels : enjeux et usages

International audienceCet article de synthèse introduit la notion de virtualisation, appliquée aux architectures reconfigurables et en recense des cas d'usage significatifs. Ces usages balaient des préoccupations aussi diverses que la durabilité des produits (gestion de l'historique) ou le support à l'expérimentation de nouveau dispositifs (promotion de l'innovation matérielle) sans négliger la mise au point d'environnements logiciels
