流处理器的相变存储器主存性能优化
Main Memory Performance Optimization of Phase Change RAM in Stream Processor
摘要
Abstract
This paper uses the Phase Change RAM(PCRAM) as the main memory of Imagine stream processor, studies the performance optimization of it. It builds the performance analysis model of PCRAM. In order to enhance the limited PCRAM write endurance, it uses redundant bit-writes removal technology to extend the endurance of PCRAM to an average 3.4x longer. It uses nonvolatile feature to avoid not necessary row buffer write back. It analyzes the memory access schedule algorithms, and results show that the row/open memory access schedule algorithm is suitable for PCRAM.关键词
