Load Value Approximation

Joshua San Miguel, Mario Badr, Natalie Enright Jerger
2014 2014 47th Annual IEEE/ACM International Symposium on Microarchitecture  
Load value approximation can also inhibit approximated loads from accessing memory, resulting in energy savings.  ...  As memory accesses consume substantial latency and energy, we explore load value approximation, a microarchitectural technique to learn value patterns and generate approximations for the data.  ...  We compare load value approximation (LVA) to load value prediction (LVP) and prefetching.  ...

2014 Proceedings of the 23rd international conference on Parallel architectures and compilation - PACT '14  
This technique predicts the value of safe-to-approximate loads when they miss in the cache without tracking mispredictions or requiring costly recovery from misspeculations.  ...  We define a new microarchitecturally-triggered approximation technique called rollback-free value prediction.  ...  When an approximate load misses in the cache, the value predictor intercepts the event and generates a prediction value.  ...

RFVP: Rollback-Free Value Prediction with Safe-to-Approximate Loads

We introduce an approximation technique, called Rollback-Free Value Prediction (RFVP). When certain safe-to-approximate load operations miss in the cache, RFVP predicts the requested values.  ...  To mitigate the bandwidth wall, RFVP drops some fraction of load requests which miss in the cache after predicting their values.  ...  Approximate loads which hit in the cache (usually a common case) return the correct value.  ...
