EXP

Mnemonic Operation Instruction coding
EXP C * EXP(ACC) + D CCCCCCCCCCCCCCCCDDDDDDDDDDD01100
Description

EXP will multiply 2^ACC with C and add the constant D to the result.

Since ACC (in it’s role as the destination for the EXP instruction) is limited to linear values from 0 to +0.99999988, the EXP instruction is limited to logarithmic ACC values (in it’s role as the source operand for the EXP instruction)  from –16 to 0. Like the LOG instruction, EXP will treat the ACC content as a S4.19 number. Positive logarithmic ACC values will be clipped to +0.99999988 which is the most positive linear value that can be represented within the accumulator.

D is intended to allow the linear ACC to be offset by a constant in the range from –1 to +0.9990234375
