WebThe solutions to the cache coherency problem usually include invalidating all but one of the duplicate lines when the line is modified. Although the hardware uses snooping logic to invalidate, without any software intervention, any processor whose cache line has been invalidated will have a cache miss, with its attendant delay, the next time that line is … Webproposes a software solution for memory coherency in MPSoCs. The approach relies on the programmer intervention for mapping local and shared variables and segments. Using uncached accesses for the shared segments, the cache coherency and memory consistency can be maintained at no hardware cost.
