About:
ICSILog is a C-language implementation of a fast
single-precision approximation of the natural
logarithm with adjustable accuracy. The core idea
is to use a quantized version of the mantissa of
the input floating point number as a pointer into
a lookup table. The amount of quantization of the
mantissa determines the table size and therefore
the accuracy. Current processors are able to store
relatively large lookup tables in cache memory.
Therefore an acceptable accuracy can be reached
without too many main memory accesses.
