Originally developed to connect processors and memories in multicomputers, prior research and design of interconnec-tion networks have focused largely on performance. As these networks get deployed in a wide range of new applications, where power is becoming a key design constraint, we need to seriously consider power efficiency in designing(More)
Due to the wire delay constraints in deep submicron technology and increasing demand for on-chip bandwidth, networks are becoming the pervasive interconnect fabric to connect processing elements on chip. With ever-increasing power density and cooling costs, the thermal impact of on-chip networks needs to be urgently addressed. In this work, we first(More)
Due to wire delay scalability and bandwidth limitations inherent in shared buses and dedicated links, packet-switched on-chip interconnection networks are fast emerging as the pervasive communication fabric to connect different processing elements in many-core chips. However, current state-of-the-art packet-switched networks rely on complex routers which(More)
Until very recently, microprocessor designs were computation-centric. On-chip communication was frequently ignored. This was because of fast, single-cycle on-chip communication. The interconnect power was also insignificant compared to the transistor power. With uniprocessor designs providing diminishing returns and the advent of chip multiprocessors (CMPs)(More)
This paper addresses battery-aware static scheduling in battery-powered distributed real-time embedded systems. As suggested by previous work, reducing the discharge current level and shaping its distribution are essential for extending the battery lifespan. We propose two battery-aware static scheduling schemes. The first one optimizes the discharge power(More)
Many scheduling techniques have been presented recently which exploit dynamic voltage scaling (DVS) and dynamic power management (DPM) for both uniprocessors and distributed systems, as well as both real-time and non-real-time systems. While such techniques are power-aware and aim at extending battery lifetimes for portable systems, they need to be(More)
With ever-increasing power density and cooling costs in modern high-performance systems, dynamic thermal management (DTM) has emerged as an effective technique for guaranteeing thermal safety at run-time. While past works on DTM have focused on different techniques in isolation, they fail to consider a synergistic mechanism using both hardware and software(More)
