(
|
|
Multiplying two 16-bit numbers yields a 32-bit number.
|
|
MUL2 returns the lowest 16 bits, we want the highest.
|
|
|
|
We split each short into hi and lo bytes, then sum
|
|
the following multiplications:
|
|
|
|
31..24 23..16 15..08 07..00
|
|
{ ahi * bhi }
|
|
{ alo * bhi }
|
|
{ ahi * blo }
|
|
{ alo * blo }
|
|
|
|
Bits 07..00 can be ignored, but each sum in bits 23..16
|
|
can end up overflowing into bit 24.
