Computation Types Rn = EXP Rx (EX) Function Extracts the exponent of the fixed-point operand in Rx, assuming that the operand is the result of an ALU operation. The exponent is placed in the shf8 field in register Rn. If the AV status bit is set, a value of +1 is placed in the shf8 field to indicate an extra bit (the ALU overflow bit). If the AV status bit is not set, the exponent is calculated as the two’s-complement of: # leading sign bits in Rx – 1 ASTATx/y Flags SZ Set if the extracted exponent is 0, otherwise cleared SV Cleared SS Set if the exclusive OR of the AV status bit and the sign bit (bit 31) of the fixed-point operand in Rx is equal to 1, otherwise cleared SHARC Processor Programming Reference 11-81
