Energy Efficient Dual Issue Embedded Processor
Journal Title: EAI Endorsed Transactions on Industrial Networks and Intelligent Systems - Year 2016, Vol 3, Issue 6
Abstract
While energy efficiency is essential to extend the battery life of embedded devices, performance cannot be ignored. High performance superscalar embedded processors are more energy efficient than low performance scalar processors, however, they consume more power which is very limited in battery operated deeply embedded industrial devices. In this paper we propose an energy efficient dual issue embedded processor that can deliver up to 60% improvement in IPC (instructionper- cycle) performance with less than 20% increase in power consumption compared to a single issue scalar processor. In contrast to traditional multi-issue embedded processors that use power intensive superscalar techniques to extract instruction-level parallelism from applications, the proposed processor uses simple hardware techniques to resolve instruction scheduling conflicts. The processor is optimized for implementation on a low cost FPGA which makes it a suitable candidate for cost sensitive embedded industrial applications.
