SoD: Enabling Design Strategies for Single Chip Heterogeneous Multiprocessors

在接下来的十年里，将有可能在单个芯片上提供足够的晶体管用于大约100个32位RISC处理器。这些新兴的、软件密集的单芯片异质多处理器(SCHM)计算机系统的设计排除了简单分析或指定和综合方法的可能性。对于硬件/软件混合的单芯片多处理系统，还没有发展出一门设计科学。战略性计算机系统组织--需要一个不能自动进行创造性过程，因此必须在系统级别促进这种设计者的创造性。这项研究的全部愿景是发展所需的科学，使未来的设计系统能够摆脱当前CAD工具的指定和综合思维模式，成为仍然与当前较低级别的集成电路设计方法学流程相联系的特征和发明范例。我们研究背后的另一个主要主题是，计算机系统设计人员从趋势分析开始，寻找应用程序集主要功能的预期变化与执行这些变化的系统的主要体系结构功能的物理能力之间的未来交叉点。在这些基础上，设计策略被发明出来，它们可以成为整个可编程系统类的基本组织主题。

Abstract0438948Paul, JoAnn M. CMUSoD: Enabling Design Strategies for Single Chip Heterogeneous MultiprocessorsWithin the next ten years, it will be possible to provide enough transistors on a single chip for on the order of a hundred 32-bit RISC processors. The design of these emergent, software-intensive single chip heterogeneous multiprocessor (SCHM) computer systems precludes the possibility of seat-of-the-pants analysis or specify-and-synthesize methodologies. No science of design has been developed for mixed hardware/software single chip multiprocessing systems. Strategic computer system organization - requires a creative proces that can not be automateds,and thus this designer creativity must be facilitated at the system level. The full vision of this research is to develop the science needed to enable future design systems to break away from the specify-and-synthesize mind set of current CAD tools to become a characterize-and-invent paradigm that still has ties into the current lower level integrated circuit design methodology flows. Another major theme behind our research is that computer system designers start from trend analyses, looking for future cross-over points between anticipated changes in the major features of applications sets and the physical capabilities of the major architectural features of the systems that carry them out. From these, design strategies are invented which can become basic organizing themes for entire classes of programmable systems.
