Abstract
Abstract Recent trends of increasing core-count and bandwidth/memory wall have motivated researchers to explore novel memory technologies for designing processor components such as cache, register file, shared memory, and so on. Domain-wall memory (DWM), also known as racetrack memory, is a promising emerging technology due to its non-volatility and very high density. However, use of DWM presents challenges due to characteristics of both DWM itself (eg, requirement of shift operations, variable latency) and processor ...
