Abstract

This paper presents a fault tolerant and energy efficient write-back set-associative cache, which has a heterogeneous structure. The cache architecture is based on partitioning the ways of each set into two different parts. In each set, one cache way uses SEC-DED code and maintains dirty blocks while the other ways employ parity bit and keep clean blocks. To evaluate the set-associative cache, SIMPLESCALAR tool and CACTI analytical model are used. The experimental results show that as the feature size decreases and the associativity increases, the energy saving of the proposed cache increases. The experimental results express that for an 8-way set-associative cache in 32nm, about 7% area and 2%-17% energy consumption are saved. These figures are achieved by keeping the reliability in the same level of the conventional SEC-DED protected cache.
DSM技术的容错和低能量回写异构集关联缓存
提出了一种具有异构结构的容错节能回写集关联缓存。缓存架构基于将每个集合的方式划分为两个不同的部分。在每个集合中,一种缓存方式使用SEC-DED代码并维护脏块,而另一种方式使用奇偶校验位并保持干净块。为了评估集合关联缓存,使用了SIMPLESCALAR工具和CACTI分析模型。实验结果表明,随着特征尺寸的减小和关联度的增加,所提缓存的节能效果有所提高。实验结果表明,对于32nm的8路集合关联缓存,可节省约7%的面积和2% ~ 17%的能耗。这些数字是通过将可靠性保持在传统的SEC-DED保护缓存的同一级别来实现的。
