CIRCA-GPUs: Increasing Instruction Reuse Through Inexact Computing in GP-GPUs

Abbas Rahimi, Luca Benini, Rajesh K. Gupta
2016 IEEE design & test  
The instruction reuse recalls the outcome of an instruction on a hardware table; therefore, a processor can reuse it temporally if the processor performs the same instruction with the same input values  ...  Modern applications including graphics, multimedia, web search, and data analytics offer massive parallelism and significant degrees of tolerance to inexact computing.  ...  These techniques rely upon the tolerance in the output precision of multimedia algorithms to achieve high reuse rates, and work at the granularity of the floating-point (FP) instruction [11] , or a region  ...
