We explore load value approximation, a micro architectural technique to learn value patterns and generate approximations for the data.

Load value approximation estimates data values to save the processor from needing to retrieve the actual values from memory. These approximate values must be�...

Oct 1, 2014 � To overcome this latency, we use a load value approximator, a hardware mechanism that estimates memory values. By approximating the load value�...

Approximate value locality: ➢ Many data values are similar to or can be approximated from previously seen values. Page 12. Outline. • Load Value�...

Load value approximation can also inhibit approximated loads from accessing memory, resulting in energy savings. On a range of PARSEC workloads, we observe up�...

Load Value Approximation. 1. Load X misses in L1 Cache. 2. Load Value Approximator generates X_Approx. 3. Processor pretends X_Approx was returned on a “hit”. 4�...

Approximate data storage: ➢ Reducing SRAM power by lowering supply voltage [Flautner, ISCA 2002]. ➢ Reducing DRAM power by lowering refresh rate [Liu,�...

Load value approximation can also inhibit approximated loads from accessing memory, resulting in energy savings. On a range of PARSEC workloads, we observe up�...

Oct 20, 2015 � Load value approximation can also inhibit approximated loads from accessing memory, resulting in energy savings. On a range of PARSEC workloads,�...
