SHARC EXP Instruction

Hi ,

Apologies for the delay.

This Exp instruction extracts the exponent of the operand in register Rx. If the number of leading sign bits in Rx is n, the result in Rn is  –(n–1). For example,
(1) R5 = EXP R3;

>>> If R3 = 0xE4000000 then R5 = -2

>>> If R3 = 0x00000101 then R5 = -22

(2) R5 = EXP R3 : 2 ;

>>> If R3 = 0x140056A3 and R2 = 0x87654321 then R5 = -2 (in hexadecimal, R5=0xFFFFFFFE)
