// Double precision (DP) loads are straight forward.
// To get rid of the mathematical discontinuity in the ieee number system,
// We add the implicit bit and change the zero exponent from x000 to x001.
// This needs to be undone when data is stored.
//
// the spec says that Single Precision loads (SP) should be fully normalized
// and converted to double format before storing.
// there is not time to do that, so we take a short cut and deal with the problems
// when the operand is used.
// The Double precision exponent bias is 1023.
// The Single precision exponent bias is 127.
// The difference x380 is added to convert the exponent.
// (actually no adder is needed)
// x380 => "0_0011_1000_0000
// SP Dddd_dddd
// if D=0 0_0011_1ddd_dddd --> {D, !D, !D, !D}
// if D=1 0_0100_0ddd_dddd --> {D, !D, !D, !D}
//
// also for SP -> SP_infinity is converted to DP infinity
// -> (0) is converted to x381 (instead of x380) and the implicit bit is added.
// so .... there are now 2 numbers that mean zero
// 1) (exp==x001) and (IMP_bit==0) and (FRAC==0)
// 2) (exp==x381) and (IMP_bit==0) and (FRAC==0)
// the only time the SP load needs correcting (prenormalization) is
// (exp==x381) and (IMP_bit==0) and (FRAC==0) <== SP denorm can be converted to DP norm.
