## Overview

Intrinsics to operate on floating point/integer scalar values, configuration, conversions, addressing, locks and events.

Note
  For floating point scalar operations like add, subtract, multiply and compare, these can either be mapped on 'vector floating point' or on 'softfloat lib'
  - by Default, softfloat lib implementation will be chosen which takes quite a few cycles since its emulated.
  - AIE_OPTION_SCALAR_FLOAT_ON_VECTOR flag can be used in application (pre-processor macro) to map these operation on vector floating point datapath to reduce number of cycles.
  For floating point non-linear scalar operations like sine/cosine, sqrt and inv, these can either be mapped on 'scalar non-linear unction' or on 'runtime lib (math.c)'
  - by Default, runtime lib implementation will be chosen which takes quite a few cycles since its emulated.
  - AIE_OPTION_SINF_COSF_FAST flag can be used in application (pre-processor macro) to map these operations on scalar non-linear functions to reduce number of cycles.
