2-way table, H table for value larger than 1/4 L table for value smaller than 1/4, H table for remaining We have this only for the q15_t version. It does not make sense to have it for q7_t type

This file include the declaration of common tables. Most of them are used for activation functions

+

Assumption: Unified table: input is 3.x format, i.e, range of [-8, 8) sigmoid(8) = 0.9996646498695336 tanh(8) = 0.9999997749296758 The accuracy here should be good enough

+

2-stage HL table:

+

The entire input range is divided into two parts:

+

Low range table: 0x000x xxxx or 0x111x xxxx table entry will be the binary number excluding the first two digits, i.e., 0x0x xxxx or 0x1x xxxx

+

High range table 0x0010 0000 – 0x0111 1111 0x1000 0000 – 0x1101 1111

+

For positive numbers, table entry will be 0x0010 0000 – 0x0111 1111 minus 0x0010 0000 i.e., 0x0000 0000 - 0x0101 11111

+

same thing for the negative numbers, table entry will be 0x1000 0000 – 0x1101 1111 minux 0x0010 0000 i.e., 0x0110 0000 - 0x1011 1111
