umulExtended — perform a 32- by 32-bit multiply to produce a 64-bit result
void umulExtended(
|
genUType x, |
| genUType y, | |
| out genUType msb, | |
out genUType lsb); |
void imulExtended(
|
genIType x, |
| genIType y, | |
| out genIType msb, | |
out genIType lsb); |
x
Specifies the first multiplicand.
y
Specifies the second multiplicand..
msb
Specifies the variable to receive the most significant word of the product.
lsb
Specifies the variable to receive the least significant word of the product.
umulExtended and imulExtended perform multiplication of the two 32-bit integer
quantities x and y, producing a 64-bit integer result. The 32 least
significant bits of this product are returned in lsb and the 32 most significant bits are returned
in msb. umulExtended and imulExtended perform
unsigned and signed multiplication, respectively.
