TheA/WA/Wunits refer to the current (in Ampère) produced per Watt of light incident on the photodiode. This current-production happens when the diode operates in the so-called photoconductive mode. Since your question wasn't on the inner workings of a photodiode, I won't expand on this, butWikipediacontains some more information if desired.
Variousbasic block vectorization (SLP)improvements, such as better data dependence analysis, support of misaligned accesses and multiple types, cost model.
Superword level parallelism (SLP) is an advanced method of traditional vectorization that facilitates parallelism across loop iterations, SIMD, and basic blocks.Vectorizationin this context is the process used to complete several similar tasks (or instructions) simultaneously, therefore saving processing time and resources.
