Syntax:

• LUTLOGM Rd3 BS Rs1

Description:

Returns in Rs3 the number which has the same mantissa as the number provided in register Rs1, while the exponent field is set to:

• 0x3FF, if (1.mRs1 <= 1.5)

• 0x3FE, if (1.mRs1 > 1.5)

Instruction is performed according to BS (bank select) and is stack.

Microcode Pattern:

Takes 4 cycles to execute.
    Example: LUTLOGM 0xA3 3 0xA1

	  
	MPC  BS3 C3 P3 P1
	-----------------
	LGM   0  0  00 A1
	 -    0  0  00 00
	 -    0  0  00 00
	 -    3  0  A3 00

	  

Exceptions :

Exceptional cases are handled as specified in table below (in all these cases, mantissa is set to zero):

Sign	ERs1(hex)	ERs3(hex)	Exceptions
0	0x7FF	0x7FF	BADOP
0	0	0x7FF	OVF
1	x	0x7FF	OVF
