Abstract

Power consumption in Complementary Metal Oxide Semiconductor (CMOS) technology has escalated to a point that only a fractional part of many-core chips can be powered-on at a time. Fortunately, this fraction can be increased at the expense of performance through the dark-silicon solution. However, wi

Highlights

  • Aggressive transistor scaling with technology has fuelled an unprecedented growth in the number of Processing Elements (PE) available in modern Systemson-Chip (SoCs)

  • The proposed technique operates by storing a part of the physical address in tag arrays while the conversion between the virtual address and physical address is performed by the Translation Lookaside Buffer (TLB)

  • This paper introduced techniques which can be implemented in DSCSs to reduce power consumption whilst considering performance and avoiding high temperature

Introduction

Aggressive transistor scaling with technology has fuelled an unprecedented growth in the number of Processing Elements (PE) available in modern Systemson-Chip (SoCs). Prior works only focus on distributing application tasks in different regions on the chip without considering the performance of the applications Another alternative solution is through Dynamic Thermal Management (DTM) techniques such as power-gating, Dynamic Voltage Frequency Scaling (DVFS) and Task migration. MultiLevel Caches (MCA) and the Network-on-Chip (NoC) paradigm have replaced single-level caches and buses respectively as the standard components for many-core future chip designs [1,2,3,4] These components increase the power consumption and impacts heavily on the temperature of the chip.
